If two events `Aa n dB` are such that `P(A^o)=0. 3 ,P(B)=0. 4 ,a n dP(AnnB^o)=0. 5` , then find the value of `P[B//(AuuB^o)]dot`

Text Solution

Verified by Experts

The correct Answer is:
`1//4`
`P[B//(AuuB')]=(P(Buu(AuuB')))/(P(AuuB'))`
`=(P(AuuB))/(P(A)+P(B')-P(AnnB'))`
`=(P(A)-P(AnnB'))/(P(A)+P(B')-P(AnnB'))`
`=(0.7-0.5)/(0.8)=1/4`
