If A and B are two events such that `P(A)=0. 3 ,\ P(B)=0. 6\ a n d\ P(B//A)` `=0. 5` find `P(A//B)\ dot`

Text Solution

Verified by Experts

`P(A)=0.3`

`P(B)=0.6`

` P(B / A)=0.5=frac{P(A cap B)}{P(A)}`

` P(A cap B)=0.5 times P(A)=0.15`

` P(A / B)=frac{P(A cap B)}{P(B)}`

`=frac{0.15}{0.6}=0.25=frac{1}{4}`
