Sorry, I meant permutations, so there a N!/(N-K)! ways to select K tiles from a bag of N.

Or for 7 of 100 tiles = 100*99*98*97*96*95*94 permutations.

I think it will be easier to calculate the probabilities of the different combinations rather than count them, but it's still going to be a fair amount of work.
