23. A and B are two independent events such that `P(A) = 1/2 and P(B)=1/3`. Then P (neither A nor B) is equal to

A

`1-P(A/B)`

B

`1-P(A/overset(" "-)(B))`

C

`(1-P(AcupB))(P(B))`

D

`(P(overset(" "-)A))/(P(overset(" "-)B))`

Text Solution

Verified by Experts

The correct Answer is:
B
Since , `P(A//bar(B)) +P(bar(A)//bar(B)) =1 `
`P(bar(A)//bar(B))=1-P(A//bar(B))`
