If two events A and B are such that `P (A) > 0 and P (B) != 1`, then `P (barA/barB)` is equal to

A

`1-P(A//bar(B))`

B

`1-P(bar(A)//B)`

C

`(1-P(A nn B))/(P(bar(B)))`

D

`(P(bar(A)))/(P(bar(B)))`

Text Solution

Verified by Experts

The correct Answer is:
A
We know that, `P(A//bar(B))+P(bar(A)//bar(B))=1`
`rArr " " P(bar(A)//bar(B))=1-P(A//bar(B))`
