2.4: Combinations and the Binomial Theorem
...The binomial theorem gives us a formula for expanding (x + y)n, where n is a nonnegative integer. The coefficients of this expansion are precisely the binomial coefficients that we have used to count combinations....

Combinations, Pascal's Triangle and Binomial expansions
...You can pick the y from any of our three (x + y) binomials and x 's from the rest. For example, if we choose the y from the third binomial we get x x y; if we choose the second we get x y x, and if we choose the first we get y x x. Since there are three (x + y) factors and we are choosing one y, here are 3C1 different combinations....
