+65 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
+23252 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?
