If two A and B such that P(A) gt 0 and ...

If two A and B such that ` P(A) gt 0 and P(B) ne 1`, then `P(barA//barB)` is equal to :

A

`1-P(A//B)`

B

`1-P(barA//barB)`

C

`(1-P(AuuB))/(P(barB))`

D

`(P(A))/(P(barB))`

Text Solution

Verified by Experts

The correct Answer is:
C
`P(barA//barB)=(P(barAnnbarB))/(P(barB))=(P(bar(AuuB)))/(P(barB))=(1-P(AuuB))/(P(barB))`
