discrete math functions

There are 52 different cards in a deck. How many different hands of 5 cards each are possible?

I tried nchoosek(52,5), but the question also mentions that every hand can be arranged 120 different ways, so I am confused.

Thank you

I think that is just telling you that 5!=120

nchoosek(52,5) is equal to 52!/(52-5)! 5!

so nchoosek() already accounts for that.
