C(7,7)=7! (7-7)
C(n,r)=n!(n-r)

I feel like there's more to it than that tho. lol Like there are many combinations. XD I just don't know how to figure out how many XD

Answer 8

For the first selection there's 7 choices, then the next choice there's 6, then the next, there's 5, and so on. This is what a permutation is, so you can calculate this by just doing 7! or 7 factorial. This allows you to find all the possible shuffles, which will be a large number.

As say song A is first, then we can have song B, C, D, E, F, G for slot 2, then any of ( C, D, E, F, G) in slot 3, but then you have to account for all the other options where maybe slot 1 was G, and slot 2 was E, this is how you get a very large number.
