In a hostel, 60%

Given:

Let H and E denote the number of students who read Hindi and English newspaper respectively.

Hence, P(H) = Probability of students who read Hindi newspaper= P(E) = Probability of students who read English newspaper = P (H E) = Probability of students who read Hindi and English both newspaper = (a) Find the probability that she reads neither Hindi nor English newspapers.

P(neither H nor E)

P(neither H nor E) = P(H E)

As, { H E =(H E)}

P(neither A nor B) = P ((H E))

= 1 - P (H E)

= 1- [P(H) + P(E) - P (H E)]  (b) If she reads Hindi newspaper, find the probability that she reads English newspaper.

P (E|H) = hindi newspaper reading has already occurred and the probability that she reads English newspaper is to find.

As we know  P (E|H) = (c) If she reads English newspaper, find the probability that she reads Hindi newspaper.

P (H|E) = English newspaper reading has already occurred and the probability that she reads Hindi newspaper is to find.
