Choosing 5 people (without replacement) from a group of 34 people, of which 15 are women, keeping track of the number of men chosen. A.Not binomial: the trials are not independent. B.Not binomial: there are more than two outcomes for each trial. C. Procedure results in a binomial distribution. D. Not binomial: there are too many trials.
