In the 131st running of the Kentucky Derby in 2005, there were 20 contenders. 6. How many different ways can horses place first, second, and third? WORK PLEASE!
For this question, you're going to need to do a permutation, since order matters for first, second, and third. 20P3 = 20! / (20 - 3)! = 20! / 17! = 20 * 19 * 18 = 6,840 ways.
