A science club has 16 members. How many ways can a president, a vice president, and a treasurer be selected from the members?

boyakko [2]

Answer:

The answer would be D. 3,360

Explanation:

The solution is found by multiplying 16 times 15 times 14. The club has 16 members and after one role (president) is filled, there are 15 left to fill the next (vice). The same goes for the next role (treasurer). So 16 is multiplied with 15, then 14. This is more of a math question that biology btw.
