  1. I wrote a quick Java program to generate the total amount gained from switching or not over 100,000 trials with an envelope value of 1,000. Although the random number generator isn't entirely random, I thought it might help nonetheless.
  2. If I understand this correctly, the solution is as follows:
  3. Didn't know that, thanks.
  4. Dear wolfgang, the solution that you consider correct suffers from two problems: 1) It violates common understanding of thermodynamics and 2) even if we allow such violation, it does not satisfy the conditions in your original post. Here is why While I understand that lateral and out-of-box thinking are valued around here, in general such solutions have to be internally consistent (and avoid violating explicit conditions set forth in the original post). Also, in this forum, we obey the law of thermodynamics. I don't see how that helps. Since the controlling ship still needs 5x the amount of fuel to go the same distance, it would only get 1/8 of the way before having to turn back.
  5. I was thinking that it might be interesting if there was a section in the forum for chess problems, maybe with support for chessboard pics. Not sure how difficult it would be but it might be cool.
  6. Конечно ... Веревка подбежал шкив, на одном конце была обезьяна, на другом конце вес.Два оставшихся в равновесии.Вес каната было 4 унции / футбол, а в возрасте от обезьяны и мать обезьяны составил четыре года.Вес обезьяна была много фунтов, как мать обезьяны было лет, и весом весом и весом каната вместе были в полтора раза больше, поскольку вес обезьян. Вес вес превышал вес веревки, как многие фунтов, как обезьяна лет, когда мать обезьяны был вдвое старше брата обезьяны было, когда мать обезьяны был вдвое старше брата обезьяна будет, когда брат обезьяны в три раза стара, как мать обезьяны Когда мама была обезьяна была в три раза стара, как обезьяна в пункте 1. Мать обезьяны был вдвое старше обезьяна Когда мать обезьяны был наполовину стара, как обезьяна будет Когда обезьяна в три раза стара, как мать обезьяны было, когда мать обезьяны в три раза стара, как обезьяна в пункте 1. Возраст матери обезьяны превысил возраст брата обезьяны на такую ​​же сумму, как возраст брата обезьяны превысил возраст обезьяны. Какова была длина веревки? So the rope has legs and plays footbal?! And monkey's mother is a male?! And age is money?!Was it Google translation? I guess, it'll be awhile before computers can understand and translate natural language.Although it's worth noting that about the only bit translated correctly, is that very thing, which I misunderstood. The translation states, the weight of the rope together with the weight is 1.5 times the weight of the monkey, as the problem statement intended. Whereas I understood it as half weight of the monkey. I was going to add the caveat that I cannot verify the usefulness of google translate. But yes, I thought all monkeys played football.
  7. No, Sherlock, but great investigative reporting! Oh that makes things different. In that case I think there are several solutions. Your statement is correct. Your question is valid. But since you don't yet have a unique answer, it's your question to answer. Btw, no offense intended by the Sherlock comment. None taken.
  8. Are we using your age as shown on your profile page (72)?
  9. Wow. That was fast. Good job!
  10. Just a quick math problem that shouldn't take too long. The digits 0-9 can be arranged into 3,628,800 distinct 10-digit numbers (including a leading 0). Of these, how many are prime?
  11. Sorry I haven't really been active, I haven't had a lot of time to post what with school and stuff, but I'll check in periodically and if I have anything important to say I'll say it.
