There are 20 people in a club. In how many ways can the club elect a president, a secretary and a treasurer, on person can hold more than one office?.

To determine the number of ways the club can elect a president, a secretary, and a treasurer, we need to use the concept of permutations.

Since each person can hold more than one office, we have 20 choices for the president, 20 choices for the secretary, and 20 choices for the treasurer.

To find the total number of ways, we multiply these choices together:

20 choices for president * 20 choices for secretary * 20 choices for treasurer = 20 * 20 * 20 = 8,000.

Therefore, there are 8,000 ways in which the club can elect a president, a secretary, and a treasurer.
