*[tex \LARGE {{n}\choose{k}}] (*[tex \LARGE n] choose *[tex \LARGE k]) is the number of combinations of *[tex \Large n] things taken *[tex \Large k] at a time and is calculated by *[tex \Large \frac{n!}{k!(n\,-\,k)!}]


For you:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{6!}{4!(6\,-\,4)!}]


You can do your own arithmetic.
