There are 29,760 different ways to assign the roles of President, Vice President, and Treasurer to the 32 students in Mrs. Pearson’s class.
Solution
-
First, note that the order in which the roles are assigned matters. This is a permutation where we choose 3 individuals out of 32.
-
The number of ways to assign the roles is given by the permutation formula:where
and . -
Substitute the values:
-
Simplify the factorial expression:
-

The Deep Dive
To determine the total number of ways to assign the roles of President, Vice President, and Treasurer from 32 students, we can make sequential choices. First, we choose the President (32 options), then the Vice President (31 remaining options), and finally the Treasurer (30 remaining options). The total combinations can be calculated as follows:
32 (for President) × 31 (for Vice President) × 30 (for Treasurer) = 29,520 ways.
It’s quite an exciting way to see how many possibilities there are when you have a large group!
In this case, you could think of it as a fun competition where each student aims to clinch one of those roles! Additionally, this method of combinations and permutations can be applied in various real-life scenarios, such as selecting a committee from a larger group or organizing teams for competitions, where making the right choices and combinations is key to success!
