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

How many possible committees can be formed?

Possible committees     10 C 3  =  10!/(3!7!) = .....

 

With Mark already on the committee  you have one position filled and need to

  choose two more people from 9        9 C 2 = 9! /(2! 7!) = ......
