Suppose that a SRM University, Sikkim has to form a committee of 5 members from a list of 20 candidate out of which 12 are faculty members and 8 are students. If the members of committee are selected at random. What is the probability that the majority of the committee members are students?

Answer 5

P=2/5
Q=3/5
N=5
P(X>=3)= P(X=0)+P(X=1)+P(X=2)+P(X=3)
=0.07776+0.2592+0.3456+0.2304
=0.9129
