"WebTo calculate the number of combinations with repetitions, use the following equation: Where: n = the number of options. r = the size of each combination. The exclamation mark (!) represents a factorial. In general, n! equals the product of all numbers up to n. For example, 3! = 3 * 2 * 1 = 6. The exception is 0! = 1, which simplifies equations.
