[hide]Problem 1
Prove that given attendees of a party, one can defenestrate a member times.
Solution
Proof
We use mathematical induction. We start with , which is trivial. We induct; give members defenestrated, remain. We throw out member, leaving us with members defenestrated and members remaining.
Thus lemma is true. Plugging in , we have

Problem 2
Prove that given couples, you can defenestrate couple times.
Problem 3
Jim and his wife Jeri attend a party with 4 other married couples. As they enter, Jim and Jeri shake hands with some of the guests, but not with each other. During the evening, each person except 1 shakes hands with some of the guests, but not with their spouse.
