Nine sales representatives, 6 men and 3 women, at a small company wanted to attend a national convention. There were only enough travel funds to send 3 people.

(a) Estimate the probability that randomly selecting 3 people from a group of 6 men and 3 women will result in selecting 3 women.
(b) Based on your answer to part (a), is there reason to doubt the manager’s claim that the 3 people were selected at random? Explain.
