So we need to Cem coasters. Orders is important. So this is a permutation. Um, we have 16 and we're choosing eight. So this becomes 16 times 15 times, 14 times, 13 times 12 Dems living Done Because we want to choose a way of 16 choices for the 1st 1 15 for the second, and so on and so forth. And if we do that, we know then that there are 518,918,400 possible ways that we could ride them his roller coasters.
