I have a problem doing the Binomial Probability. Yes, I know the formula, P(x)=n!/(n-x)!x! yada yada yada.

Now I am I watching the video, it is telling me that 12!/5!(7!), I should be getting 792, for my first step. And I inputed this in my TI84 I get 2.01180672e10..... Where did I go wrong? I inputed the factorial symbol but yet I got it wrong.
