Question 1181910: Two hundred people apply for a job as receptionists at a five-start hotel. Half of them have completed university while the other half have not. If the human resource department selects 3 applicants at random, find the probability that all 3 are university graduates. (Please round to three decimal places)

100 of 200 are graduates
probability is (100/200)(99/199)(98/198)=0.1231; the answer is 0.123
This is almost a coin flip and the probability of 3 heads, which would be (1/2)^3=1/8.
