If P(A)=0. 4 ,P(B)=0. 3 and P(B/A)=0. 5 ...

If `P(A)=0. 4 ,P(B)=0. 3` and `P(B/A)=0. 5 ,` find `P(AnnB)` and `P(A/B)dot`

Text Solution

Verified by Experts

given that, `p = P(A) + P(B) - P(AnnB)`
`q= P(A) + P(B) - 2*P(A nn B)`
`p-q = P(A nnB)`
`P(bar A) + P( bar B) = 1 - P(A) + 1- P(B)`
`= 2- P(A) +P(B)`
`p=(P(A)+P(B)) - (p-q)`
`2p-q = (P(A)+P(B))`
`2- (2*p - q) = 2- 2*p +q`
