There are ten people in the Baking Club, including Mark. They choose 3 people to form an executive committee.

How many possible committees could be formed that include Mark?

 

BTW the answer is not 119, 121, 45, 120, 84

Mark is already on the committee; this leaves 9 persons for the next choice and 8 persons for the third choice.

9 x 8  =  72.

Well, since Mark is already on the committee, which leaves 9 people to choose the remaining two. In how many ways can you choose 2 people out of 9?  You can choose 2 people out of 9 in: 9 C 2 =36 ways.

 

That is my best attempt! What have YOU done to get the "right answer"? Can you show us your attempt?
