उत्तर

Assertion is true and Reason is false.

Explanation:

Given, n(A) = n(B)

`P(A/B) = (n(A ∩ B))/(n(B))`

And `P(B/A) = (n(A ∩ B))/(n(A))`   

= `(n(A ∩ B))/(n(B))`

`P(A/B) = P(B/A)`   ...[∵ n(A) = n(B)]

So, Assertion is true.

Mutually exclusive events have no intersection, making the conditional probability zero.

So, Reason is false.
