Text Solution

Verified by Experts

The correct Answer is:
N/a

Let `H=` event of passing in Hindi
`E=` event of passing in English
Given that
`P(HnnE)=0.5, P(E)=0.75`
and `P(HuuE)'=0.1`
`implies1-P(HuuE)=0.1`
`P(HuuE)=0.9`
`impliesP(H)+P(E)-P(HnnE)=0.9`
`impliesP(H)+0.75-0.5=0.9`
`impliesP(H)=0.65`
`:.` Probability of passing in Hindi `=0.65`
