There are 8 ways to select a first place finisher
Then 8-1 = 7 ways to pick the horse for second place; since we cannot have the first place person repeat.
For third place, there are 8-2 = 6 ways
This process keeps going until we hit 1
We have this count down: 8,7,6,5,4,3,2,1
Multiplying those values out will get the final answer
8*7*6*5*4*3*2*1 = 40,320
We can shorten this to factorial notation
8! = 40,320
