# What field involves N Choose K type probems? [closed]

My guess is that it is a sub-field of Discrete Math known as combinatorics but I cannot find it here.

it's "discrete" math, not "discreet" math. They are two very different words. – Bean Oct 16 '11 at 19:14
Note that the number $\binom{n}{k}$ "n choose k" is a Binomial coefficient and that you find on your Wikipedia link. – t.b. Nov 8 '11 at 0:20
