In how many wYs can a chairperson and a vice chairperson be selected from a committee of 15 senators?

15P2 = 15*14

To find the number of ways a chairperson and a vice chairperson can be selected from a committee of 15 senators, you can use the concept of permutations.

In this case, since the order in which the chairperson and vice chairperson are selected matters, we need to calculate the number of permutations.

The total number of ways to select the chairperson is 15, as there are 15 senators to choose from. After selecting the chairperson, there are 14 remaining senators to choose from for the position of vice chairperson.

To find the total number of ways, we need to multiply the number of choices for each position. Using the rule of permutations, we multiply the number of choices for each position:

Number of choices for chairperson: 15
Number of choices for vice chairperson: 14

Total number of ways: 15 * 14 = 210

Therefore, there are 210 ways to select a chairperson and a vice chairperson from a committee of 15 senators.
