Yahtzee is a game of chance like dice or poker. The numbers of ways the outcomes ( straight rolling ) is 240 .
Probability of hitting a large straight is 240 / 7776 = 1/32
Yahtzee is the one of dice game that uses five standard six-sided dice. After rolling each die, the player can decide which die to keep and which to reroll. Goals include many different types of combinations, many of which originate from poker.
The two types of combinations that players must roll are called roads: small roads and large roads. Similar to poker straights, these combinations consist of consecutive dice. A small straight uses 4 out of the 5 dice and a large straight uses all 5 dice. Since the dice rolls are random, we can use probability to analyze the likelihood of hitting large straight on a single roll. Assumes that the dice used are fair and independent of each other. Now, you need to know how many ways you can roll a big/ large straight. Here it is more difficult than calculating the sample size. Big straights are harder to roll than small straights, but it’s easier to count the number of times you’ve rolled a big straight than the number of times you’ve rolled a small straight.
Next, determine the number of ways to get a straight by rolling the given dice. To get a nice straight with dice {1, 2, 3, 4, 5}, you can arrange the dice in any order. It turns out that you just swap the five dice. There are 5! = 120 ways to do this. There are two dice combinations that form the large Straight, each with 120 ways to roll, so there are 2 x 120 = 240 ways to roll the large Straight.
Now the probability of hitting a big/ large straight can be calculated with simple division. Since there are 240 ways to get the big straight in one roll, and 7776 rolls 5 dice, the odds of getting the big straight are 240/7776, close to 1/32, and lie 3.1%.

a salesperson has found that the probability of a sale on a single contact is approximately .03. if the salesperson contacts 100 prospects, what is the approximate probability of making at least one sale?
The probability of making no sales in 100 tries is 0.97^100. That's equal to about 0.0476, so the probability of getting at least one sale is 0.9524. About 95%.
If the probability of making a sale is 0.03 then the probability of not making a sale must be 1-0.03 which is 0.97.
So looking at contacting 100 prospects, you could say there are two general outcomes. Either the salesman makes no sales at all, or he makes at least one sale. There are no other possible outcomes, so the probability of those two outcomes must add up to 1.
So the probability of making of at least one sale is 1 minus the probability of making no sales.
The probability of making no sales in 100 tries is 0.97^100. That's equal to about 0.0476, so the probability of getting at least one sale is 0.9524. About 95%.

Mr. Giordano's drove 4.5 miles in 5 minutes. Mr. Baras drove 6.3 miles in 8 minutes. Who drove faster? Explain using unit rates for both teachers.
If Mr. Giordano's drove 4.5 miles in 5 minutes and Mr. Baras drove 6.3 miles in 8 minutes, then the Mr. Giordano drove fast because speed of Mr. Giordano is greater than Mr. Baras
The distance traveled by Mr. Giordano = 4.5 miles
The time taken = 5 minutes
Speed = Distance / Time
Substitute the values in the equation
Speed = 4.5/5
= 0.9 miles per minutes
The distance traveled by Mr. Baras = 6.3 miles
The time taken = 8 minutes
Speed = Distance / Time
Substitute the values in the equation
Speed = 6.3/8
= 0.78 miles per minutes
Hence, if Mr. Giordano's drove 4.5 miles in 5 minutes and Mr. Baras drove 6.3 miles in 8 minutes, then the Mr. Giordano drove fast because speed of Mr. Giordano is greater than Mr. Baras

P(A). P(Y)= 0.5*0.6=0.3
Probability: - Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.
Number of cases of A, N(A)= 250,
So,
P(A)=250/500 =0.5
and
N(Y)= 300, so P(Y)=300/500 =0.6
N(A and Y)= 175 so P(A and Y)= 175/500=0.35
A and Y are mutually exclusive implies A and Y donot have any elements in common, but here there are 175 people who are below 30 years and under the influence of alcohol, So they are not mutually exclusive!!
For A and Y to be independent, the Probability of A intersection Y should be equal to the product of their respective probabilities,
in this case P(A). P(Y)= 0.5*0.6=0.3 which is not equal to P( A intersection Y) (0.35)
So, A and Y are not mutually Independent also.

Answer:
A = 101250 meter²
Step-by-step explanation:
Answer:
Maximum area enclosed will be 101250 meter².
Step-by-step explanation:
Let the length of the rectangular plot is x meters and the width is y meters.
900 meters is the length of the fence which represents the length of the three sides of the plot.
Therefore,
x + 2y = 900
y =  meters
Now the area of the rectangular plot will be
A = Length × Width
= (x)(y)
= 
= 450x - 
We know for the maximum area we will differentiate the area and equalize it t the zero.

= 450 - x
For the maximum area, 
Therefore, 450 - x = 0
x = 450
and y = 
y = 
y = 450 - 225
= 225 meters
Now the area enclosed A = 450 × 225
A = 101250 meter²

Linear equations - The team can bring its 24 players
What do you mean by linear equations with one variable?
A linear equation with one variable is one that can be written as ax+b = 0, where a and b are two integers, and x is a variable. This type of problem only has one solution. For instance, the linear equation 4x+4=8 only has one variable.
We are given that,
the total money raised by the lacrosse team is given to be $2863.50
bus rented at a cost of $1087.50
meal budget per person is calculated to be $74
let us assume the number of players the team can bring to the tournament to be "x".
bus rent + (meal budget * number of players) = total money raised
= 1087.50 + (74*x) = 2863.50
= 1087.50 + 74x = 2863.50
= 74x = 2863.50 - 1087.50
= 74x = 1776
= x = 1776 ÷ 74
= x = 24
Thus the team can bring its 24 players.

Characterize the slope of the line in the graph,
A. Positive
B. Negative
C. Zero
D. Undefined
Slope of the line graph here is undefined.
When a line is vertical, its slope is ambiguous. A vertical line lacks the horizontal distance required for a positive, negative, or zero slop to exist. Since there is no horizontal change, there is no slope for vertical lines because 0 cannot be divided into any integer.
It is obvious that the x-coordinates are the same if we have a pair of coordinates, (x1, y1) and (x1, y2) through which a line passes. They are the same vertical line's points. As a result, the slope of such a line will be ambiguous.
Examples of undefined slope in real-world situations include elevators that only go up and down, and a mountain cliff that is vertical for a certain amount of height but impossible for climbers to scale.

Jonas have to repay $13888 after 4 years.
Given
Principle amount of loan (P) = $12,400
Rate of interest (R) = 3%
Time period (T) = 4 years
Also the interest is not compounded, hence it is simple interest.
The formula for simple interest is (PTR)/100
Where,
P = Principle amount
T = time period
R = rate of interest
By substituting the values in the formula we get,
Simple interest = (12400 x 4 x 3) / 100
Simple interest = 1488
Hence adding this interest to Principle sum we get
12400 + 1488 = 13888
