# Math Help - Combination/Permutation problem

1. ## Combination/Permutation problem

How many ways can 100 distinct bikes be stored in 4 distinct warehouses?

From reading some old posts on this site, I think the answer is 100!
------
4!4!4!4!

Now if the bikes are not distinct but the warehouses still are distinct?

Again, if I have gleaned info from past posts the answer should be:

c(100 + 4 - 1, 4-1) OR C(103,3) Please confirm or disconfirm. THank you!

For each bike, there is a choice of four warehouses. So the total number of possible choices is $4^{100}$.

That is correct.
