Question

HELP PLEASE How many combinations are possible to select a student president, vice president, and treasurer among 23 students? Assume a student cannot hold more than one office.

Answer 1

10,626

Explanation:

Because being the student president is different from being the treasurer, the order in which students are selected for these roles matters. Therefore, a permutation is used to calculate the number of combinations that are possible, with nPr = n/(n-r) or evaluate it by doing 23c3.
