Question 296502: How many different ways can a college select three applicants for a teaching position from a pool of 20 applicants. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! The 1st choice is 1 of 20, then 1/19, then 1/18
20*19*18 = 6840
But, choosing ABC is the same as BCA, so divide by 6
6840/6 = 1140 different ways.
