    Melchior, Caspar, and Balthazar, for sure!


    Possibly also Shadrach, Meshach, and Abednego, though who knows?

              Albert and Bernard just met Cheryl. “When’s your birthday?” Albert asked Cheryl.

              Cheryl thought a second and said, “I’m not going to tell you, but I’ll give you some clues.” She wrote down a list of 10 dates:

              May 15 — May 16 — May 19

              June 17 — June 18

              July 14 — July 16

              August 14 — August 15 — August 17

              “My birthday is one of these,” she said.

              Then Cheryl whispered in Albert’s ear the month — and only the month — of her birthday. To Bernard, she whispered the day, and only the day.

              “Can you figure it out now?” she asked Albert.

              Albert: I don’t know when your birthday is, but I know Bernard doesn’t know, either.

              Bernard: I didn’t know originally, but now I do.

              Albert: Well, now I know, too!

              When is Cheryl’s birthday?
              Code:
              As of 9/21/10:         As of 9/13/10:

                    The Albert, Bernard and Cheryl's Birthday problem looks to me a like a pretty good discrete math problem, if you arrange the dates just right. But in plain English here's how I approached it:

                    ... Cheryl then tells Albert and Bernard separately the month and the day of her birthday, respectively.

                    Albert: I don't know when Cheryl's birthday is, but I know that Bernard does not know too.
                    She gave Albert one of the months that does not have a unique date (July or August).
                    May and June are out.

                    Bernard: At first I didn't know when Cheryl's birthday is, but I know now.
                    14 is out, because Bernard can't guess July or August in order to make that statement. She gave Bernard 15, 16 or 17.
                    Albert: Then I also know when Cheryl's birthday is.
                    August is out, because Albert can't guess 15 or 17 to make that statement.
                    So 15 and 17 are out.


                    All that's left is July 16.

                        OK, so it's PowerBall fever!

                        Let's say that I buy one ticket with two entries on it, then stick it in a drawer without looking at the numbers at all.

                        Sunday morning, I wake up and hear on the news that somebody won the $800 million jackpot (let's say it is discounted to $545 million on a present value basis, and let's assume a 45% income tax rate overall, so that the net after-tax value is $300 million).

                        1) What is the minimum price I accept to sell my ticket to someone else, assuming I still haven't looked at any of the actual numbers?

                        2) Later that day, I hear on the news that the winning ticket was sold in my state, too. Now what is the minimum price I accept to sell my ticket, if I still haven't looked at it yet?

                        3) Then I hear the next morning that someone in my town was the winner. Same question, same constraint.

                        (answer may not be in actual dollars, it might be in PS (Tickets sold in my state as ratio to all tickets sold) or PT (ratio for tickets sold in town compared to all sold). Note that my one ticket has two numbers on it.

                          Better start with the assumption that you found a gopher fan who will give you money believing you have not looked at the numbers.

                                Use scalar (Ts, Tc, whatever). Assume I bought in my town. or don't bother trying at all. whichever.

                                One of the tricky parts in the problem is estimating the odds of multiple winners....
