Handshakes: Five couples, including the host and his wife, attend a party. Throughout the evening, as introductions are made, various people shake hands (except couples do not shake each others' hands).

How many hands did the host shake, and how many hands his wife shake? 3 Cards: There are 3 cards: one is all red, one is all blue, and the third is blue on one side and red on the other. The cards are shuffled. You pick one at random and it is blue on the side facing you. What are the odds that it is also blue on the other side?
