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?

 

Would the answer to this question be 10*9*8 because im not sure and am slightly confused with this question.

10 C 3 = 120 ways

 

 

10 x 9 x 8 = 720   is    10 P 3     you will get some duplicates like   a b c  a c b     c a b  c b a   b a c  b c a     (6 duplicates)   720/6 = 120
