1. suppose you randomly slect five members from a committee that consists of 8 men and 7
women. find the probability that;
a) none are men
b) atleast one is a women.
Solution
a)none are men
no. of ways of selecting 5 women from 7 women = 7C5 = 21
total ways of selcting 5 members from 15 = 15C5
total probability = 21/15C5
b)atleast one is woman
no. of ways of selecting 1 women from 5 women = 5
no. of ways of selecting 4 members from remaining 14 = 14C4
total probability = 5/14C4
