If `Aa n dB` are two events such that `P(A)=0. 5 ,P(B)=0. 6a n dP(AuuB)=0. 8` , find `P(A//B)`

Text Solution

Verified by Experts

Given: `A` and `B` are two events such that `P(A)=0.5, P(B)=0.6` and `P(A cup B)=0.8`
As we know that, if `A` and `B` are two events then
`P(A cup B)=P(A)+P(B)-P(A cap B)`

`Rightarrow 0.8=0.5+0.6-P(A cap B) `

`Rightarrow P(A cap B)=0.3`
