Question

The board of directors of a corporation must select a president, a secretary, and a treasurer. In how many possible ways can this be accomplished if there are 20 members on the board of directors?

Answer 1

Since there is a total of 20

Since we need to chose 3 position

Then we will use the permutation

nPr = 20P3

20P3 = 20 x 19 x 18

20P3 = 6840

There are 6840 ways to choose them
