If P(notA)`=0. 7 ,P(B)=0.7 a n dP(B//A)=0. 5` , then find `P(A//B)a n dP(AuuB)dot`

Text Solution

Verified by Experts

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

`0.5=frac{P(A cap B)}{0.3} = P(A cap B)=0.15`

`P(frac{A}{B})=frac{P(A cap B)}{P(B)}=frac{0.15}{0.7}=0.214`

`P(A cup B)=0.3+0.7-0.15=0.85`
