Things to think about for next time:
Problem #9 — box splitting.
Also problem #12 cup flipping — we talked about two and four cups, but what about other starting numbers of cups arranged in a circle?

Probability, Part 1 For next time, think about problems 4 (Love Triangle) and 5 (Die Throws) on page 2 of the handout, and problems 1 (Card Deck) and 10 (What a Loser!) on pages 2 and 4. (Also problem 12 — the St. Petersburg Paradox — looks fun.)
