Assessment exercise - Combinations
A committee of 6 members is to be
selected from 5 men and 9 women. Find the number of different committees that could be selected if;
There are no restrictions.
14C6= 3003.
There are exactly 3 men and 3 women on the committee.
5C3 x 9C3 = 840
There is at least 1 man on the committee.
Total – All women, 3003 - 9C6 = 2919
