    100 white marbles

    The way how the marbles were selected is not known, so you cannot do better then Bonanova. However, instead of grabbing the calculator:
  2. 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.

    @rocdocmac Pas du tout. Mais c'est ma langue maternelle, je sais même écrire.

    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:

    Grabbing marbles

    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/

    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?

    Code to the safe

    I see, I found the solution for 8 generals, confused by range() in Python. The distribution for 7 generals:

    Code to the safe

    The hard part is to generate the lock numbers from the generals, the formulas are quite complicated: There is a way to cheat: Both programs give the same list: The distribution: The solution sure is not unique, various combinations are possible. Not talking about the possibility that the lock 1 has to be unlocked to unlock locks 2 and 3.
