∙ 13y ago2 people can be selected from a pool of 7 people in (7 x 6) = 42 ways.
But each group of 2 can be selected and seated in 2 ways.
So the number of different 2-person subcommittees formed from 7 people is (42/2) = 21 .

How many different 3 person committees can be formed from a group of 8?
8.7.6/3! = 56 Here is why this works. There are 8 choices for the fist member of the committee. Then we have 7 choices for the next and 6 for the last. HOWEVER, when picking a committee, the order does not matter. So for example if we pick Chuck, Judy and Melanie and we denote them as C, J and M respectively, then one committee is CJM but that is the same committee as CMJ and MCJ. In fact, there are 3! or 3x2x1=6 ways to arrange the 3 members so we must divide 8x7x6 by 6 and the result is 56 committees of 3 people picked from 8. Picking a committee is an example of a combination problem in math. If order mattered it would be a permutation.
