A class contains 12 female and 20 male students. Find the probability that when two students are chosen randomly from the class, the first student is male and the second student is female.

Write the probability as a fraction in the simplest form.

Answers

Answer 1
3/5 for girls and 2/5 for guys
Answer 2

Answer:

15 / 62

Step-by-step explanation:

Since there 32 students, of which 20 are male, the probability of selecting a student and them being male first is 20/32.

The probability of selecting another student and they are female is 12/31, because the male student is counted out of the selection because he is already picked.

This makes the probability 20/32 x 12/31 = 15 / 62

The probability of spinning an odd number, not flipping heads, then not spinning a 6 is
__

Answers

Using it's concept, it is found that the probability of spinning an odd number, not flipping heads, then not spinning a 6 is:

[tex]p = \frac{20}{81} = 24.69\%[/tex]

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

There are 5 odd numbers in the spinner, out of 9, hence the probability of spinner an odd number is 5/9.The coin is fair, hence the probability of flipping tails = not heads is of 1/2.Out of the 9 numbers in the spinner, only one is six, hence the probability of not spinning a 6 is of 8/9.

Then, the probability of the compound event is:

[tex]p = \frac{5}{9} \times \frac{1}{2} \times \frac{8}{9} = \frac{20}{81} = 24.69\%[/tex]

-6.5


17.5-24 you place the 24 near the 17.5 and make 24 a negative so the equation would be

y= 17.5-24

Answer:

[tex] \sf \: y = 6.5[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of y.

The equation is,

→ 24 = y + 17.5

Then the value of y will be,

→ 24 = y + 17.5

→ y + 17.5 = 24

→ y = 24 - 17.5

→ [ y = 6.5 ]

Hence, the value of y is 6.5.

She will earn 150$

Step-by-step explanation:

4% = 0.04

0.04 x $625 = 25

6 x 25 = 150$

Therefore, Skye earns 150$ from interest over the course of 6 years.

Answers

Answer:

Step-by-step explanation:

We know that a straight angle is equal to 180°. Therefore, 120°+(a)=180°

We can solve for (a) by subtracting 120 from 180, which is 60.

180-120=60

m∠a+120°=180°

m∠a=60°

We know that the sum of all angles in a triangle is 180°.

Therefore, (a)+60°+(b)=180°

We know that (a) is equal to 60°, so our new equation is:

60°+60°+b=180°

60+60=120

180-120=60

m∠b+60°+60°=180°

m∠b=60°

Answers

Answer:

1: Tip, $2.23

2: Tax, $0.74

3: Total, $17.87

4: Split, $5.95

Step-by-step explanation:

To find the tip, you must multiply the tip percentage by the bill, (which has not been taxed yet). The tip is 15%, which is equivalent to 0.15. The tip multiplied by the bill (0.15×14.90) equals $2.23.

To find the tax, you do the same as you did with the tip. The tax is 5%, which equals 0.05. The tax multiplied by the bill, (0.05×14.90) equals $0.74. The total cost is the bill, tip, and tax added together, (14.90+2.23+0.74) equals $17.87. To find out how much each person will pay equally, you must divide the total bill by the amount of people, (17.87÷3) which equals $5.95.
