familiar with the combination formula?

OpenStudy (mathmale):

Read 14C5 as "Fourteen choose five" and think of it as "the number of combinations of five from a set of 12." For example, you might have a set of 12 playing cards and want to know how many different combos of 5 cards each you could possibly draw from that set. Where might you find a definition of "combinations" and the formula for the number of combinations of size r from a set of n?
