Answer :

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.


As we know



P (H|E) =
