what is the probability of getting a royal flush in poker?
I realize it is 4/C(52,5), but what are the combinations for the numerator?

Don't assume everybody knows what a royal flush is, I had to look it up
http://en.wikipedia.org/wiki/Hand_rankings#Straight_flush
There are 4 possible royal flushes.
the number of ways to choose any 5 cards
= C(52,5)
so the prob of a royal flush = 4/C(52,5)
= 4/2598960
= 1/649740
