From a group of 7 men and 6 women, five persons are to be selected to form a committee so that at least 3 men are there on the committee. What is the probability of having 0 woman in committee ? Choose the correct choice:
A) 7/36  B) 9/144  C) 1/36  D) 1/18  E) 5/18
We may have (3 men and 2 women) = (71/363 x 61/362) = 525   or (4 men and 1 woman) = (71/364 x 61/361) = 210   or (5 men only) = (71/365) = 21   Required ways = 756   Probability of having 0 woman in committee = 21 / 756 =1/36   ans - 1/36
