*[tex \LARGE \ \ \ \ \ \ \ \ \ \ {{20} \choose {16}}]


Which is the number of ways to choose 16 things from 20 things.  The number of ways to choose *[tex \LARGE k] things from *[tex \LARGE n] things is calculated with the formula:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ {{n}\choose{k}}\ =\ \frac{n!}{k!(n\,-\,k)!}]


Congratulations!  You have been randomly selected to be able to do your OWN arithmetic.
