Answer 2

Answer:

Let E and H denote the events that the student will pass in English and Hindi examination respectively.

Then, we have P(E∩H)=0.5,P(

E

ˉ

∩

H

ˉ

)=0.1 and P(E)=0.75.

Now, P(

E

ˉ

∩

H

ˉ

)=0.1

⇒P(

E

ˉ

∪

H

ˉ

)=0.1

⇒1−P(E∪H)=0.1

⇒P(E∪H)=0.9

⇒P(E)+P(H)−P(E∩H)=0.9

⇒0.75+P(H)−0.5=0.9

⇒P(H)=0.65.
