Answer:
90 different ways
Step-by-step explanation:
We have a total of 10 members, and we want to find how many groups of 2 members we can have, where the order of each member in the group of 2 is important, so we have a permutation problem.
To solve this problem, we need to calculate a permutation of 10 choose 2.
The formula for a permutation of n choose p is:
![P(n, p) = n! / (n - p)!](https://tex.z-dn.net/?f=P%28n%2C%20p%29%20%3D%20n%21%20%2F%20%28n%20-%20p%29%21)
So we have:
![P(10, 2) = 10! / (10 - 2)!](https://tex.z-dn.net/?f=P%2810%2C%202%29%20%3D%2010%21%20%2F%20%2810%20-%202%29%21)
![P(10, 2) = 10! / 8!](https://tex.z-dn.net/?f=P%2810%2C%202%29%20%3D%2010%21%20%2F%208%21)
![P(10, 2) = 10*9 = 90](https://tex.z-dn.net/?f=P%2810%2C%202%29%20%3D%2010%2A9%20%3D%2090)
So there are 90 different ways of choosing a president and a vice-president.
