If `P(A)=0. 4 ,\ P(B)=0. 8 ,\ P(B//A)=0. 6` . Find `P(A//B)` and `P(AuuB)`

Explanation

`P(A)=0.4 `

`P(B)=0.8 `

`P(B / A)=0.6 `

` P(B / A)=frac{P(A cap B)}{P(A)} `

`Rightarrow 0.6=frac{P(A cap B)}{0.4} `

`Rightarrow P(A cap B)=0.24 `

`P(A / B)=frac{P(A cap B)}{P(B)}=frac{0.24}{0.8}=0.3 `

`P(A cup B)=P(A)+P(B)-P(A cap B) `
