And you have no evidence to indicate one choice over the other. The current 50-50 condition is unrelated to a previous condition, when three chances were involved. And it doesn't matter how many times to you do it (if you follow the sequence of events you specified). If you restate the problem, and say you now remove one of three choices, leaving two that might be false, or two choices that contain at most one true, then it is a different problem. Jesus, forget mathematicians. When you need answers to difficult problems, always ask a sliver digger (a carpenter). |

I won't speak for anyone else, but when I need the answer to a difficult question (or even what may turn out to be a not so difficult question, for that matter) I think I'll ask someone who can at least make his or her position on a previous question (not to mention an explication thereof) clear. Thanks, anyway. Wolfgang still, the venture was not entirely without profit.......we have at least learned something about the origins of old expression, "to a man with a hammer......." |

![]() you said you took a false choice away That means the remaining choice is 50/50 no matter what. Any previous condition is like Wolfgang: totally irrelevant :-) |

![]() salmobytes wrote: you said you took a false choice away I said nothing of the sort. I said that I revealed one of the losing tickets. This is not the same thing at all. Firstly, I took nothing away. Secondly, there were no false choices. The only choices to be made were the player's initial pick of what he or she hoped to be the winner, mine to reveal one of the losers, and the player's to switch or stand pat. Only one of those three is subject to a value judgment that makes any sort of sense in context. The player can make the WRONG second choice, but there can be nothing "false" about it or any of the others. That means the remaining choice is 50/50 no matter what. Most people learn very early in life to get used to the fact that they will not always understand what is said to them. Those of us who are lucky also learn, eventually, that this is not really as much of a problem as it first appear, because often enough we DO understand what has been said to us.....even when those who said it clearly do not. This is one of those instances. You are absolutely right; you have no idea of what the correct solution to the problem is (despite it's having been put forward here in various guises several times), and thus your chances of correctly guessing what to do are 50/50 since there are only two possibilities to choose from. Unfortunately, for you (well, not JUST you......as we have seen here over the past few days.....as well as the past few years), you guessed the right answer to the wrong question. The question, as clearly stated in the original exposition of the problem, concerned what you SHOULD DO.....NOT your chances of guessing correctly what you should do. So, after several days, you have a fuzzy notion (at best) of what the question was, no idea of what the correct answer is, and only a dim (and wrong) notion of what you said above. Here's what you should do. Whenever tempted to say something, you should first determine whether or not you really have something to say. Then, if you meet the first condition in the affirmative, you should take some time to try to figure out whether there is any chance of determining what it is you have to say. If that yields positive results, you should then ask yourself whether it was worth the trouble and would be worth the extra trouble of trying to phrase it in a way that might be comprehensible and of interest to a reader. If so, then you should do just that, as opposed to tapping on the keyboard in a random fashion. Any previous condition is like Wolfgang: totally irrelevant :-) And yet, here you are. Wolfgang p.s. for the benefit of anyone who might still be interested in all of this, i believe it was Scott who stated early on in this thread that the MH problem hinged on the fact that the exposure of a losing ticket was not random. i agreed. on further reflection, it turns out that this is not true. as i pointed out to Jon a bit later, as long as a losing ticket comes up in the exposure, it doesn't make any difference whether that ticket was chosen deliberately or at random. this shouldn't be difficult for anyone to grasp. it's also not the interesting part. what IS interesting.....because it is SO obvious in retrospect.....is that turning up the WINNING ticket (whether by chance or deliberately) doesn't make any differece either. remember, you, the player, have been given the option of sticking with your original pick or switching. the question is "what should you do." the exposure of the winner simply makes the choice a no brainer. ![]() |
