I thought what were the odds of Sheff's wife going into labor after 8 1/2 months - I couldn't find a good answer, but it looks like she had about a 25% chance of having given birth already. She is just getting to full term now. The odds of her giving birth during the 4-day tournament would be a good question for a MA211 Statistics I final exam. My guess is about 3 to 5%. I should try to figure it out.
