3. For example, given {Andy, John, Julia}. We want to pick 2 people to give a gift: we can pick {(Andy, John), (Andy, Julia), (John, Julia)}, so there are 3 ways. So we can list and count.
4. Or we could do this with the formula C(3, 2)=
5. C(8, 6)=
So there are C(8,6)=28 ways of chosing 6 out of 8 people to form the subcommittees. <span />

To answer this question, we just need to subtract the saved cloth from the requested cloth:
Since the fractions don't have the same denominator, we have to find the least common denominator. Luckily, since 6 goes into 12 twice, we can convert
into 
:
Now that the fractions have a common denominator, we can subtract them:
The difference between the requested cloth and the saved cloth is 5/12 of a foot, or 0.4166'.
