Please read the notes from class on binomial coeffiecients and answer question at end.

On wednesday we talked about statements that look paradoxical (self-contradictory), statements that are actually paradoxes and Russell's paradox.
We also saw a proof of the fact that the number of subsets of a set of n elements equals 2^n using the binomial formula.
Please review the binomial formula before coming to class next wednesday.
