PART 1 MODULE 5. FACTORIALS, PERMUTATIONS AND COMBINATIONS. n! "n factorial". If nis a positive integer, then n!is nmultiplied by all of the smaller positive integers. Also, 0! = 1. 0! = 1. 1! = 1. 2! = (2)(1) = 2. 3! = (3)(2)(1) = 6. 4! = (4)(3)(2)(1) = 24. 5! = (5)(4)(3)(2)(1) = 120. 6! = (6)(5)(4)(3)(2)(1) = 720. 7! = (7)(6)(5)(4)(3)(2)(1) = 5,040. 8! = (8)(7)(6)(5)(4)(3)(2)(1) = 40,320. 9! = (9)(8)(7)(6)(5)(4)(3)(2)(1) = 362,880. 10! = (10)(9)(8)(7)(6)(5)(4)(3)(2)(1) = 3,628,800. n! is n multiplied by all of the positive integers smaller than n. FACT: n! is the number of different ways to arrange ( PERMUTATIONS of) n objects.
We could also use the permutation formula, since forming a three letter code word requires us to choose and arrange three elements from a set of five elements. Solution to #2 ... example, 10-13-10, 8-12-2, 2-12-8 are three different possibilities.) 2. How many possibilities would there be if …
