My question is how can I solve this problem; The sales force of a business consists of 10 men and 10 woman. A production unit of 5 people set up at rsandom. What is the probability that it will include atleast one woman?

Men = 10C10

Women = 10C1

20 in all

A production unit of 5 people set up at random = 20C5

P(1 women) = 10C1 / 20C5

P(1 women) = 10 / 15504

Hence the probability of one women will be

P(1 women) = 6.44
