Question

Calculate the number of ways that an executive board consisting of a president, a vice president, and a secretary-treasurer can be selected from a group of 17 students. a) 289 ways b) 680 ways c) 867 ways d) 2,448 ways

Answer 1

Explanation:

17 P 3 = 17! / 14! = 4080 ways

Though the answer that is given 17 C 3 = 17! / ( 14!*3!) = 680 is incorrect . I believe....because the order matters....
