Statistics TI 83

Does anyone know how to enter 8! into a TI 83 calculator?

Even better yet would be to enter the formula 62C5 with the 62 and 5 being lower case.

nCr = N!/(N-R)!R!.

I dunno but I got the Ti89 so all I do is type nCr(62,5) and I get 6,471,002.
8! is 40320. Do you have a math menu? It's listed under probability on mine.

I've used this page in the past and it was pretty helpful. Don't know if it has what you need on there.

Thanks, I shouid have known it was under probabilities. That is where some of the other Stat functions are located.

That will be much quicker than 62 * 61 * 60 * 59 * 58.
