 Combinatorics Permutations without repetition Let us suppose a finite set A is given. The permutation of the elements of set A is any sequence that can be formed from its elements. The number of permutations is: Pn=n! (n factorial), where n is the number of elements of the set. Given three people {Michael, Peter, Rose}, the following is the set of all permutations of that set: {Michael, Peter, Rose}, {Michael, Rose, Peter}, {Peter, Michael, Rose} {Peter, Rose, Michael}, {Rose, Michael, Peter}, {Rose, Peter, Michael} There are no other permutations of this set besides those listed. Using the formula: P3=3!=6 Enter the number of elements of the set A and the computer will calculate you how many permutations without repetition of the elements are there? Enter the number n = Pn =
