"To analyze this problem we represent this senario as a random variable on a roulette wheel. The roulette wheel on the left simulates the Let's Make a Deal game. The inner wheel represents the number of the door that the car is behind, the middle wheel represents the door that is selected by the contestant, and the outer wheel represents the door Monty Hall can show. Spinning this roulette wheel once is equivalent to playing the game once. The outer wheel also tells you what your strategy should be to win. The red means that in order to win the contestant needs to switch doors, and the blue means that the contestant should not switch. Notice that there are twice as many red sections as blue. In other words, you are twice as likely to win if you switch than if you don't switch! What this wheel makes evident is that with probability 1/3 the contestant selects the correct door in which case it would be better not to switch. In the other 2/3 of the cases, Monty Hall is telling the contestant where the car is!" http://math.ucsd.edu/~crypto/Monty/images/wheel.jpg How is this an explanation?: "Notice that there are twice as many red sections as blue. In other words, you are twice as likely to win if you switch than if you don't switch!" Anyone? Anyone? TM |

I've read this before and disagree with it. And decided that Marilyn vos Savant is a skanky whore. As I read the explanation, the odds don't change if there is no interference -- i.e., if you pick one of three doors, and I eliminate a wrong door, the odds of you getting the right door by switching are 50/50. The statistics change if Monty Hall is telling you to switch. And I think that this is not a matter of probability, but a matter of statistics -- the two are different and the difference is important; probability is math, statistics is history. The problem immediately gets into an area where statistics becomes useless -- Monty knows where the car is. What if he doesn't like you? Is constipated and cranky that day? Had a booze-and-hooker filled night and makes a mistake? Anyway, that's my 2 cents. |
