WebAug 4, 2003 · The formula for the number of times a letter appears in all possible combinations is n!/ (r! (n-r)!) * r / n == c * r / n. Using the above example, it would be 15 * 4 / 6 = 10 times. All the letters {A, B, C, D, E, F} appear 10 times as shown. You can count them yourself to prove it. Now, go on to the source code section.
