I think this is a dumb question but if I have 25 categories and each category can either have a value of 1 or 0.  How many combinations do I get?

Thanks,
Montrof

I think you mean "permutations," not combinations. You have 25 slots, with two possibilities per slot. That means you will have 2^25 possible permutations.

Actually, I might be off on my "permutation" remark. Stats & Prob was a few years ago  = )
