Binomial Distribution
OK, how do I use the nCr key? google and my revision guide are yielding no clues...
so;
n=total number of... umm... trials is it?
r=number of the things you want...?
so if i wanted to do... i dont know. i can't even think of an example where i would use this at the moment.
any help would be appreciated. thanks.
