A hiring manager for an engineering firm needs to fill 10 positions. She has narrowed the potential candidates down to a group of 20. among the 10 she will ultimately choose, she wants to be sure she selected the 5 best engineers.
so it is hypergeometric distribution and not binomial because there is a finite number of places to be filled. and a success in the context of the problem would be the hiring manager selected the 5 best engineers out of the group of 20.
calculate the probability that the hiring manager chose all 5 of the best engineers
calculate the probability that she chose only 2 of the best engineers
calculate the probability that she chose at least 2 of the best engineers
