**Reiny**, Wednesday, July 27, 2011 at 10:07amThis would be an example of the C(n,r) that I explained in a few posts below.

You are choosing 9 from the 13, and the order really does not matter, so

C(13,9) = 13!/(9!4!) = 715

look for a key labeled_{n}C_{r}on your calculator

press

13

2ndF_{n}C_{r}

9

=

you should get 715
