![]() wrote in message ... I don't see how it's (objectively) counter-intuitive, and I think attempting to get too involved in "math" (beyond the basic) makes it more, rather than less difficult - for example, if it had been 4 boards, two were turned over revealing losers, and then the choice to change were given, to me, common sense indicates the odds say change your pick because of the same reasons I feel it does with 3. If you must have "math," I'm fairly sure the formula would be that the odds in favor of switching are pretty close to if not exactly x-1/x and the odds in favor of sticking are always exactly 1/x, when x is greater than 2, but I'm not a mathematician, so ??? Perhaps the odds in favor need to account for the first pick when x is higher than 3 - such that it isn't quite x-1/x - but it's always going to be better odds than 1/x. ****, that's confusing...that's why, IMO, algebra isn't the way to figure this out. About the only thing I can figure is that it is much like many threads on ROFF in that most folks, myself included at times, don't always _read_ what they are "reading," but rather, um, infer from what is written by what they _think_ is being said. In this case, they are simply ignoring that there are 3, not 2, boards and therefore, the chances cannot be 1 in 2. No comment on any of that. I just wanted to repost it because it may be the most beautiful thing I've ever seen! ![]() Heck, given the "game" as outlined by Wolfgang, there's nothing presented in the "rules" preventing the person from choosing the revealed losing board - they were simply offered a chance to change their pick. It would be the chooser making the obvious choice not to choose it because they can clearly see they won't win (they don't need to know that the chance of winning is 0 in 3). Um.....well, o.k., this may be even beautifuler. Wolfgang hoo boy! |
