In each of the Exercises choose the correct answer. If A and B are events such that `P(A/B)=P(B/A)`, then
(a) `AsubB` but `A!=B`
(b) `A = B`
(c) `AnnB=phi`
(d) `P (A) = P(B)`

Text Solution

Verified by Experts

It is given that, `P(A/B)=P(B/A)`
⇒ `P(B)P(AnnB)= P(A)P(AnnB)`
⇒`P(A)=P(B)`
Then `D` is the correct option
