If A and B are events such that P(A)= ...

If A and B are events such that `P(A)= 0.4 , P(B) =0,8 " and " P(B//A) =0.6` then `P(A//B)=?`

A

`0.2`

B

0.3

C

0.4

D

0.5

Text Solution

Verified by Experts

The correct Answer is:
B
`P(B//A) =(P(A nnB))/(P(A)) rArr P(A nnB) =0.6 xx 0.4 =0.24`
`:. P(A //B) = (P(A nnB))/(P(B)) =(0.24)/(0.8) =(24)/(80)=(3)/(10) =0.3`
