  1. It is not because of the gender. the Claytons indicates that Mrs Clayton is still alive and Jasper's mom is deceased. Therefore, Jasper is not a Clayton.
  2. In the same way, you exclude that Jasper is a Clayton: 2. In deference to an influential family member, the Claytons agreed that if they ever had a daughter they would name her Janice.
  3. There are 8 boxes, not 4. And there is another possible distribution you have to exclude.
  4. The way how the marbles were selected is not known, so you cannot do better then Bonanova. However, instead of grabbing the calculator:
  5. Tried to send you a private message, got an error. Tried admin@brainden, got suggestion you box is full.

    A big step forward. Now that we found the result, it remains to find the way to find the result.

  8. I see now: plainglazed's formula is the simplification of my formula I was so hard looking for. On paper, I got a kind of unreadable proof, so I fed them into my computer. Up to n=30, no difference with 6 decimals.

    Nice try, but they do not share and they survive all. Hint:
  10. Though they are similar, I see at least one huge difference. In the traffic jam puzzle, you cut ANY part. In the marble problem, you cut the REMAINING part. Enough for different formulae. Remains me of http://brainden.com/forum/topic/18168-squirrel/

    A large colony of squirrels dug holes during the summer and in each hole, they put between 1 and 100 nuts (each quantity has the same probability). If each squirrel has to eat 100 nuts during the winter, how many holes must he find (in average)? Each hole contains 50.5 in average, so 2 should be enough, right?
