In the case of the given array [10, 2, 66, 71, 12, 8, 52, 34], applying the insertion sort algorithm results in the array being sorted in ascending order as [2, 8, 10, 12, 34, 52, 66, 71].

To sort the given array [10, 2, 66, 71, 12, 8, 52, 34] in ascending order using the insertion sort algorithm, the following steps can be followed:

Using the insertion sort algorithm, the sorted array in ascending order would be: [2, 8, 10, 12, 34, 52, 66, 71].

Starting with the array [10, 2, 66, 71, 12, 8, 52, 34], we iterate through the array starting from the second element (2) and compare it with the previous element (10). Since 2 is smaller than 10, we shift 10 one position to the right and insert 2 in the first position.

Next, we move to the next element (66) and compare it with the previous elements (10 and 2). Since 66 is greater than both, we leave it in its position.

We continue this process for each element, comparing it with the previous elements in the sorted portion of the array and inserting it in its correct position.

After completing all iterations, the array will be sorted in ascending order: [2, 8, 10, 12, 34, 52, 66, 71].

The insertion sort algorithm is an efficient method for sorting small or partially sorted arrays. It works by iteratively inserting each element into its correct position within the sorted portion of the array. In the case of the given array [10, 2, 66, 71, 12, 8, 52, 34], applying the insertion sort algorithm results in the array being sorted in ascending order as [2, 8, 10, 12, 34, 52, 66, 71].

Disks are widely used in DBMS due to their large storage capacity and persistent storage, providing cost-effective long-term storage. However, they have slower access speed and are susceptible to failure.

Disks are widely used in a Database Management System (DBMS) due to several advantages they offer over main memory and tapes.

1. Storage Capacity: Disks provide significantly larger storage capacity compared to main memory. Databases often contain vast amounts of data, and disks can store terabytes or even petabytes of information, making them ideal for managing large-scale databases.

2. Persistent Storage: Unlike main memory, disks provide persistent storage. Data stored on disks remains intact even when the system is powered off or restarted. This feature ensures data durability and enables long-term storage of critical information.

3. Cost-Effectiveness: Disks are more cost-effective than main memory. While main memory is faster, it is also more expensive. Disks strike a balance between storage capacity and cost, making them a cost-efficient choice for storing large databases.

4. Secondary Storage: Disks serve as secondary storage devices, allowing efficient management of data. They provide random access to data, enabling quick retrieval and modification. This random access is crucial for database operations that involve searching, sorting, and indexing.

Relative Disadvantages:

1. Slower Access Speed: Disks are slower than main memory in terms of access speed. Retrieving data from disks involves mechanical operations, such as the rotation of platters and movement of read/write heads, which introduce latency.

This latency can affect the overall performance of the DBMS, especially for operations that require frequent access to disk-based data.

2. Limited Bandwidth: Disks have limited bandwidth compared to main memory. The data transfer rate between disks and the processor is slower, resulting in potential bottlenecks when processing large volumes of data.

3. Susceptible to Failure: Disks are physical devices and are prone to failures. Mechanical failures, manufacturing defects, or power outages can lead to data loss or corruption. Therefore, implementing appropriate backup and recovery mechanisms is essential to ensure data integrity and availability.

In summary, disks are widely used in DBMS due to their large storage capacity, persistence, and cost-effectiveness. However, their relative disadvantages include slower access speed, limited bandwidth, and susceptibility to failure.

DBMS designers and administrators must carefully balance these factors while architecting and managing databases to ensure optimal performance, reliability, and data integrity.

To solve this problem using the Substitution Method, we need to follow these steps:

Draw the recursion tree:

           n

        / | | | \

     n/2 n/4 n/8 n/8

    /|\

 n/4 n/8 n/16

  .......

This tree will keep dividing the input size until it reaches the base case of T(1)=c.

Show the shape of the overall tree:

The tree has a binary branching structure, and each node has four children except for the leaf nodes.

Estimate the depth of the shallowest part of the tree:

The shallowest part of the tree is at level 0, which has only one node with an input size of n. Therefore, the depth of the shallowest part of the tree is 0.

Estimate the depth of the deepest part of the tree:

The deepest part of the tree is at the leaf nodes, where the input size is 1. The input size decreases by a factor of 2 at each level, so the number of levels is log_2(n). Therefore, the depth of the deepest part of the tree is log_2(n).

Guess the big-Oh complexity order of the recursive algorithm:

Based on the above estimates, we can guess that the big-Oh complexity order of this algorithm is O(nlogn).

Prove the guess using the substitution method:

Base Case: We have T(1)=c, which satisfies O(1) = O(1).

Inductive Hypothesis: Assume that T(k) <= cklogk holds for all k < n.

Inductive Step: We need to show that T(n) <= cnlogn. Using the recurrence relation, we have:

T(n) = T(n/2) + T(n/4) + T(n/8) + T(n/8) + n

<= c(n/2)log(n/2) + c(n/4)log(n/4) + c(n/8)log(n/8) + c(n/8)log(n/8) + n

= cnlogn - c(n/2)log2 - c(n/4)log4 - c(n/8)log8 - c(n/8)log8 + n

Since log2, log4, and log8 are all constants, we can simplify the above equation as:

T(n) <= cnlogn - cn - 2cn - 3cn/4 + n

<= cnlogn - (7/4)cn + n

We need to show that there exists a constant c' such that T(n) <= c'nlogn. Therefore, we choose c' = 2c, and we have:

T(n) <= cnlogn - (7/4)cn + n

<= 2cnlogn - (7/2)cn

<= c'nlogn

This completes the proof. Therefore, the big-Oh complexity order of this recursive algorithm is O(nlogn).

Sure, I'd be happy to help!

A Karnaugh map (or K-map) is a useful tool in Boolean algebra to simplify expressions. It's used to minimize logical expressions in computer engineering and digital logic.

Your Boolean expression is `E = A’B’C’D + A’CD + A’C’ + C`. This is a 4-variable function, with variables A, B, C, and D. We will use a 4-variable K-map to simplify it.

A 4-variable K-map has 16 cells, corresponding to the 16 possible truth values of A, B, C, and D. The cells are arranged such that only one variable changes value from one cell to the next, either horizontally or vertically. This is known as Gray code ordering. Here's how the variables are arranged:

```

CD\AB | 00 | 01 | 11 | 10 |

---------------------------

00   |    |    |    |    |

01   |    |    |    |    |

11   |    |    |    |    |

10   |    |    |    |    |

```

Now, let's fill in the values from your expression:

1. `A’B’C’D`: This term corresponds to the cell where A=0, B=0, C=0, D=1. So, we will fill a "1" in this cell.

2. `A’CD`: This term corresponds to the cells where A=0, C=1, D=1. There are two cells that match this because B can be either 0 or 1. So, we will fill "1"s in both of these cells.

3. `A’C’`: This term corresponds to the cells where A=0, C=0. There are four cells that match this because B and D can be either 0 or 1. So, we will fill "1"s in all of these cells.

4. `C`: This term corresponds to the cells where C=1. There are eight cells that match this because A, B, and D can be either 0 or 1. So, we will fill "1"s in all of these cells.

After filling in the values, your K-map should look like this:

```

CD\AB | 00 | 01 | 11 | 10 |

---------------------------

00   | 1  | 1  | 1  | 1  |

01   | 1  | 1  | 1  | 1  |

11   | 1  | 1  | 1  | 1  |

10   | 1  | 1  | 1  | 1  |

```

Looking at the K-map, we see that all cells are filled with "1", which means your simplified Boolean expression is just `E = 1`. In other words, the function E is always true regardless of the values of A, B, C, and D.

In order to predict which applicants will be unsuccessful and provide support, the CIE database should consider including fields such as academic performance, extracurricular activities, demographic information, reference letters, and application essays.

To predict applicant success, several fields in the spreadsheet may be relevant for analysis. Firstly, academic performance metrics such as GPA or exam scores can provide an indication of applicants' scholastic abilities and dedication to their studies. Additionally, considering extracurricular activities can be insightful, as involvement in clubs, sports, or volunteer work may reflect applicants' leadership skills, time management, and commitment.

Demographic information should also be included to identify any potential biases or disparities in the selection process. Factors such as gender, ethnicity, or socio-economic background can help ensure fair evaluation and highlight any systemic inequalities that might impact applicants' success.

Reference letters from teachers or mentors can offer valuable perspectives on an applicant's character, work ethic, and potential. These letters provide qualitative insights that complement quantitative data. Application essays or personal statements can also be significant, allowing applicants to express their motivation, goals, and unique qualities.

In terms of analysis, a combination of regression analysis and data visualization techniques can be useful. Regression analysis can help identify the key factors that contribute to success or failure by examining the relationship between different fields and the outcome of application decisions. Visualization techniques, such as scatter plots or box plots, can provide a comprehensive overview of the data patterns and relationships, helping to identify any trends or outliers.

By considering these relevant fields and conducting analysis using regression and visualization, the CIE staff can gain insights into the factors that contribute to applicant success or failure. This information can then be used to provide targeted support and resources to applicants who are predicted to be unsuccessful, increasing their chances of achieving a positive outcome.

To implement the np.trapz() function to calculate the area under a graph of p(λ) against λ, you need to provide two arrays: p and λ. The p array represents the values of p(λ) at different points, and the λ array represents the corresponding values of λ.

Here's a step-by-step explanation of how to use np.trapz() in Python to calculate the area under the curve:

Import the necessary libraries:

import numpy as np

import matplotlib.pyplot as plt

Define the p and λ arrays. These arrays should have the same length, and each element of p should correspond to the value of p(λ) at the same index in λ.

λ = np.array([λ1, λ2, λ3, ..., λn])  # Array of λ values

p = np.array([p1, p2, p3, ..., pn])  # Array of p(λ) values

Replace λ1, λ2, ..., λn with the actual values of λ and p1, p2, ..., pn with the actual values of p(λ) at those points.

Plot the graph of p(λ) against λ (optional but recommended for visualization):

plt.plot(λ, p)

plt.xlabel('λ')

plt.ylabel('p(λ)')

plt.title('Graph of p(λ) against λ')

plt.show()

Use np.trapz() to calculate the area under the curve:

area = np.trapz(p, λ)

The np.trapz() function takes two arguments: the array of p values and the array of λ values. It computes the area using the trapezoidal rule, which approximates the area under the curve by dividing it into trapezoids.

The result is stored in the area variable, which will give you the approximate area under the curve of p(λ) against λ.

Note that the accuracy of the result depends on the density of points in the λ array. To obtain a more accurate approximation, you may need to increase the number of points or decrease the spacing between them.

Also, keep in mind that the p and λ arrays should be sorted in ascending order of λ for np.trapz() to work correctly. If they are not sorted, you can use np.argsort() to sort both arrays simultaneously:

sort_indices = np.argsort(λ)

sorted_λ = λ[sort_indices]

sorted_p = p[sort_indices]

area = np.trapz(sorted_p, sorted_λ)

By following these steps, you can use np.trapz() to calculate the area under a graph of p(λ) against λ in P

           int value = list.get(i);

           list.set(i, value - decreaseBy);

       }

   }

}

In the above code, we first create an ArrayList of type Integer called "numbers." We then prompt the user for input using the getInput() method, which uses the Scanner class to read the input from the console. The fillArrayList() method is then called, which fills the ArrayList with random values within the specified range [25, 95). The ArrayList is printed using the println() method. Next, we prompt the user for another input using getInput() to determine the value by which we want to decrease each element. The decreaseArrayList() method is then called, which decreases each element of the ArrayList by the specified value. Finally, we print the modified ArrayList using println(). This code allows you to dynamically specify the number of values to generate and the value to decrease by, providing flexibility and interactivity in the program.

The implementation in Java involves creating a Singleton class with a private constructor, a static instance variable, and a static method to access the instance. The class diagram would include a single class representing the Singleton, with appropriate attributes and methods.

1. The Singleton design pattern is used to restrict the instantiation of a class to a single object. In this scenario, we want to ensure that only one instance of a person/client is logged into the system, even in a multithreading environment.

2. The class diagram would consist of a single class representing the Singleton, let's name it "PersonSingleton." This class would have private attributes such as username and password to store the login credentials. It would also have a static instance variable of type PersonSingleton to hold the single instance of the class. The instance variable should be declared as volatile to ensure visibility in a multithreading environment.

3. The PersonSingleton class would have a private constructor to prevent direct instantiation. Instead, it would provide a static method, such as getInstance(), to access the single instance of the class. The getInstance() method would check if the instance variable is null, and if so, it would create a new instance. Otherwise, it would return the existing instance.

4. Here is an example implementation in Java:

public class PersonSingleton {

   private static volatile PersonSingleton instance;

   private String username;

   private String password;

   private PersonSingleton() {

       // Private constructor

   }

   public static PersonSingleton getInstance() {

       if (instance == null) {

           synchronized (PersonSingleton.class) {

               if (instance == null) {

                   instance = new PersonSingleton();

               }

           }

       }

       return instance;

   }

   // Getters and setters for username and password

   public String getUsername() {

It appears that the passwords listed in the dump are hashed using various algorithms, as evidenced by the different hash values. However, without knowledge of the original plaintext passwords, it's impossible to definitively determine the type of hashing algorithm used.

The level of protection offered by the mechanisms used to hash the passwords depends on the specific algorithm employed and how well the passwords were salted (if at all). Salt is a random value added as an additional input to the hashing function, which makes it more difficult for attackers to use precomputed hash tables (rainbow tables) to crack passwords. Without knowing more about the specific implementation of the password storage mechanism, it's difficult to say what level of protection it offers.

To make cracking much harder for hackers in the event of a password database leak, organizations can implement a number of controls. These include enforcing strong password policies (e.g., minimum length, complexity requirements), using multi-factor authentication, and regularly rotating passwords. Additionally, hashing algorithms with high computational complexity (such as bcrypt or scrypt) can be used to increase the time and effort required to crack passwords.

Based on the information provided, it's not possible to determine the organization's password policy (e.g., password length, key space, etc.). However, given the weak passwords in the dump (e.g., "password" and "123456"), it's likely that the password policy was not robust enough.

To make breaking the passwords harder, the organization could enforce stronger password policies, such as requiring longer passwords with a mix of upper- and lower-case letters, numbers, and symbols. They could also require regular password changes, limit the number of failed login attempts, and monitor for suspicious activity on user accounts.

Among the three major sociological perspectives the perspective that I understand the best is functionalism. Functionalism focuses on the interdependence of different parts of society.

Functionalism views society as a complex system made up of various interconnected parts that work together to maintain social order and stability. It emphasizes the functions performed by different social institutions and how they contribute to the overall functioning of society. For example, in the context of education, functionalism would analyze how schools socialize students by teaching them important values, norms, and skills, and how education prepares individuals to assume specific roles in the workforce.

As for the visual representation of my culture, I identify with the subculture of being an avid fan of a particular music genre. In this case, I would choose a visual representation of the punk rock culture, characterized by its distinctive fashion style, rebellious attitude, and a strong sense of community among its followers. Punk rock culture is a subculture within the larger society, as it has its own unique values, norms, and practices that differentiate it from the mainstream culture.

Material culture refers to the physical objects and artifacts associated with a particular culture. In the case of punk rock culture, examples of material culture could include band t-shirts, leather jackets.

Symbolic culture, on the other hand, refers to the shared meanings, values, beliefs, and norms within a culture. In punk rock culture, symbolic culture can be seen in the lyrics and music of punk rock songs, which often convey messages of rebellion, anti-establishment sentiments, and social critique.

In conclusion, functionalism provides insights into how different parts of society work together for its overall functioning and stability. A real-world example of functionalism is the analysis of education as a social institution.

}

```

This program prompts the user to enter their name and their body temperature for the last three hours, ensuring that the temperature values are within the range of 36.0-42.0. It calculates the maximum temperature using the `maxTemp()` function and then determines if the user might have COVID-19 or not using the `COVID19()` function. Finally, it displays the maximum temperature and the corresponding message based on the temperature readings.

Please note that in the `COVID19()` function, the logic is based on the assumption that a temperature of 37.0 or higher indicates a potential COVID-19 case. You can modify this logic according to the specific guidelines or requirements of your application.

Output: True if and only if there is a cover C of U such that |C| ≤ k.

In the Set Cover problem, the input consists of a universe U, which is a set of elements, subsets S1, S2, ..., Sm of U, and an integer k. The goal is to determine if there exists a set cover C of U such that the size of C is less than or equal to k.

A set cover C is a collection of subsets from S1, S2, ..., Sm such that their union is equal to the universe U. In other words, every element in U must be covered by at least one subset in C.

The problem asks whether there is a cover C that satisfies this condition and has a size (number of subsets) less than or equal to k.

The output of the problem is "True" if such a cover exists, and "False" otherwise.

To solve the Set Cover problem, various algorithms and techniques can be employed, such as greedy algorithms, integer programming, or approximation algorithms, depending on the complexity and size of the problem instance.

The problem is commonly encountered in computer science and optimization, with applications in areas such as scheduling, resource allocation, facility location, and network design, among others. It is known to be NP-hard, meaning that there is no known efficient algorithm to solve it in the general case. Therefore, researchers often focus on developing approximation algorithms or heuristics to find near-optimal solutions.

Polymorphism is important because it allows for code reusability, flexibility, and abstraction in programming.Polymorphism promotes code modularity and simplifies the maintenance and scalability of software.

Two main problems associated with aliases in computer programs are:

a. Name clashes or conflicts: Aliases can lead to ambiguity or confusion when multiple variables or entities have the same name or reference, making it difficult to determine which one is being referenced or modified.

b. Side effects and unintended modifications: Aliases can cause unintended changes to data or variables due to shared references. Modifying an alias can inadvertently affect other parts of the program, leading to unexpected behavior or bugs. Managing aliases requires careful tracking and control to prevent such issues.

Pros of reference counting: Immediate reclamation of memory when an object is no longer referenced. Deterministic behavior and predictable memory usage.

Cons of reference counting: Overhead of maintaining reference counts, which can impact performance. Difficulty in handling reference cycles, where objects reference each other and cannot be garbage collected even if they are no longer needed.

The Pennsylvania agency's program encountered a discrepancy in population prediction due to different endianness between the Motorola and Intel processors, affecting the interpretation of the input value.

The Pennsylvania agency encountered a problem with a population forecast program when running it on Intel machines, resulting in an overly large prediction for the U.S. population in 2013. The issue lies in the difference in processors used, specifically between the Motorola processor used by the Population Studies Institute and the Intel processors used by the agency.

The discrepancy arises from a difference in the representation of integers on these processors. The value 0x1D2F37E8 is a 32-bit unsigned integer, but the interpretation of this value differs between the processors due to their endianness. Endianness refers to the byte ordering of multi-byte data types in memory.

Motorola processors typically use big-endian byte ordering, while Intel processors commonly use little-endian byte ordering. In this case, when the agency's program on the Intel machines tries to interpret the value, it reads it in a different byte order, resulting in a different and incorrect interpretation of the integer.

To resolve the issue, the agency's program needs to account for the difference in endianness between the processors or ensure consistent byte ordering during data transmission and interpretation.

The error you encountered in your Scheme code arises from attempting to apply the car procedure to the symbol 'a, which is not a pair and therefore violates the contract of car.

To resolve this issue, you need to modify your code to handle the case when the input is not a list. Here's an updated version of the code:

scheme

Copy code

(define (invert lst)

 (cond

   ((null? lst) lst)

   ((pair? lst)

    (append (invert (cdr lst)) (list (invert (car lst)))))

   (else lst)))

This modified code checks if the input lst is a pair before recursively applying the invert procedure. If it is not a pair (i.e., it's an atom), the original value is returned as is. This change allows the procedure to handle symbols like 'a correctly.

The invert procedure follows a recursive approach to reverse the given list. It checks the base case of an empty list and returns it unchanged. If the input is a pair, it recursively applies invert to both the cdr and car of the list. The reversed cdr is then appended with the reversed car as a singleton list. This process continues until the entire list is reversed, including any sublists within it. Overall, this modified code should resolve the error and correctly reverse lists, including sublists, in Scheme.

(c) Analysis of the best-case scenario for Insertion sort:

In the best-case scenario, the input array is already sorted or nearly sorted. The best-case time complexity of Insertion sort occurs when each element in the array is already in its correct position, resulting in the inner loop terminating immediately.

In this case, the outer loop will iterate from the second element to the last element of the array. For each iteration, the inner loop will not perform any swaps or shifting operations because the current element is already in its correct position relative to the elements before it. Therefore, the inner loop will run in constant time for each iteration.

As a result, the best-case time complexity of Insertion sort is O(n), where n represents the number of elements in the input array.

(d) Analysis of the order of growth of T(n):

Given the recursive definition of T(n) as T(1) = 10 and T(n + 1) = 2n + T(n) for n > 1, we can expand the terms as follows:

T(1) = 10

T(2) = 2(1) + T(1) = 2 + 10 = 12

T(3) = 2(2) + T(2) = 4 + 12 = 16

T(4) = 2(3) + T(3) = 6 + 16 = 22

Observing the pattern, we can generalize the recursive formula as:

T(n) = 2(n - 1) + T(n - 1) = 2n - 2 + T(n - 1)

Expanding further, we have:

T(n) = 2n - 2 + 2(n - 1) - 2 + T(n - 2)

= 2n - 2 + 2n - 2 - 2 + T(n - 2)

= 2n - 2 + 2n - 4 + ... + 2(2) - 2 + T(1)

= 2n + 2n - 2n - 2 - 4 - ... - 2 - 2 + 10

= 2n^2 - 2n - (2 + 4 + ... + 2) + 10

= 2n^2 - 2n - (2n - 2) + 10

= 2n^2 - 2n - 2n + 2 + 10

= 2n^2 - 4n + 12

As n approaches infinity, the highest power term dominates the function, and lower-order terms become insignificant. Therefore, the order of growth of T(n) is O(n^2).

(e) Analysis of the order of growth of the expression Edi (for i = 1 to n):

The expression Edi (for i = 1 to n) represents a sum of terms where d is an integer greater than 1. To analyze its order of growth, we can expand the sum:

Edi (for i = 1 to n) = E(d * 1 + d * 2 + ... + d * n)

= d(1 + 2 + ... + n)

= d * n * (n + 1) / 2

In this expression, the highest power term is n^2, and the coefficients and lower-order terms become insignificant as n approaches infinity. Therefore, the order of growth of the expression Edi (for i = 1 to n) is O(n^2).

The sequences were created using NumPy functions. Sequence 'a' was generated using `np.arange`, 'b' and 'd' using `np.linspace` and `np.r_`, and 'c' using both `np.arange` and `np.linspace`.

1. Sequence 'a' was created using `np.arange(11)` to generate values from 0 to 10. The `np.arange` function generates a sequence of numbers based on the specified start, stop, and step parameters.

2. Sequence 'b' was generated using `np.arange(-7, 18, 2)` to create values from -7 to 17, incrementing by 2. This generates the desired sequence with odd numbers starting from -7.

3. Sequence 'c' was initially created using `np.arange(0, 2.5, 0.5)` to generate values from 0 to 2, incrementing by 0.5. This creates the sequence 0, 0.5, 1, 1.5, and 2.

4. Alternatively, sequence 'c' can be generated using `np.linspace(0, 2, 5)`. The `np.linspace` function creates an array of evenly spaced values over a specified interval. In this case, it generates 5 values evenly spaced between 0 and 2.

5. Similarly, sequence 'a' can also be created using `np.linspace(0, 10, 11)`. The `np.linspace` function generates 11 values evenly spaced between 0 and 10, inclusive.

6. Likewise, sequence 'b' can also be created using `np.linspace(-7, 17, 13)`. This generates 13 values evenly spaced between -7 and 17, inclusive.

7. To create sequence 'b' using `np.r_`, we can use `np.r_[-7:18:2]`. The `np.r_` function concatenates values and ranges together. In this case, it concatenates the range -7 to 18 (exclusive) with a step size of 2.

8. Similarly, sequence 'c' can be created using `np.r_[0:2.5:0.5]`. It concatenates the range 0 to 2.5 (exclusive) with a step size of 0.5.

9. Sequence 'd' was generated using `np.arange(0, -19, -3)` to create values from 0 to -18, decrementing by 3. This generates the desired sequence with negative values.

10. Alternatively, sequence 'd' can be created using `np.linspace(0, -18, 4)`. The `np.linspace` function generates 4 values evenly spaced between 0 and -18, inclusive.

11. Similarly, sequence 'd' can also be created using `np.r_[0:-19:-3]`. It concatenates the range 0 to -19 (exclusive) with a step size of -3.

By using these NumPy functions, we can generate the desired sequences efficiently and easily.

c) The game does not have a saddle point because there is no single outcome where both players have their best possible strategies.

d) To determine the optimal mixed strategy solution, we can use the concept of the minimax strategy. Player A aims to minimize their maximum possible loss, while Player B aims to maximize their minimum possible gain.

To find the optimal mixed strategy solution, we can calculate the expected payoffs for each player by assigning probabilities to their available strategies. In this case, Player A can choose A1 with probability p and A2 with probability (1-p), while Player B can choose b1 with probability q and b2 with probability (1-q).

By setting up and solving the respective equations, we can find the optimal values of p and q that maximize Player A's expected payoff and minimize Player B's expected payoff.
