Question

P(A) =0.20 P(B) = 0.25 P(A and B) = 0.10. What is P(B/A)?

A. 0.25
B. 0.40
C. 0.50
D. 0.05

Answer 1

c is the answer

Explanation:

Answer 2

Final answer is
`P(B/A)=0.5`

Explanation:

Given that P(A) =0.20

P(B) = 0.25

P(A and B) = 0.10.

Now we need to find about what is the value of P(B/A).

P(A and B) = P(A) * P(B/A)

Plug the given values into above formula:

`0.10=0.20\cdot P(B/A)`

`(0.10)/(0.20)=P(B/A)`

`0.5=P(B/A)`

`P(B/A)=0.5`

Hence final answer is
`P(B/A)=0.5`
