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. In how many ways can it be done?
Options:
(A) 624
(B) 702
(C) 756
(D) 812
(E) 832 Stream of consciousness:
Total men are 7
Total women are 6 so we select 5 peoples in both and at least 3 are men
7c3*6c2+7c4*6c1+7c5*6c0 then we get the 756
Thus, the answer is (C).
