A baking club wants to form an executive committee. There are $15$ people in the baking club, including Mark. In how many ways can the baking club form an executive committee with $2$ people, not including Mark?
Excluding Mark, there are 14 members left to choose from.
There are 14 choices for the first member of the committee.
After the first is chosen, 13 choices are left for the second.
14 x 13 = 182 ways to form the committee.
