There are 20 cars in a race. How many different ways can the cars finish in order in the top 3 positions?

Since there are 20 cars in a race, and asked to order in top 3 positions, we can start by multiplying down from 20, four times.

20 x 19 x 18 x 17 = 116,280

So there are 116,280 different ways the cars can finish in that order.

Hope this helps :)
