Question

P(A) = .20 P(B) = .25 P(A and B) = .10 What is P(B given A)

Answer 1

`P((B)/(A) ) = 0.5`

Explanation:

Explanation:-

Given P(A) = 0.20 and P(B) = 0.25 and P( A∩ B) = 0.10

By using conditional probability

The probability of B given A

`P((B)/(A) ) = (P(A n B))/(P(A))`

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

`P((B)/(A) ) = 0.5`
