It does indeed state that, what it does NOT state is that the host INTENTIONALLY PICKED a non-winning door. >I am the host of a TV program and you are the guest. This is the deal: >there are 3 doors. Behind one of them is $100 million. Behind the other two are a dead catfish and a dead pickerel respectively. >I invite you to select a door. You choose any one of the three: call it x. >I open another door, and say, Had you selected door y, you would have won a dead catfish. That is the original message, word for word, as stated in Arthur's email. The last sentence is the crux of the matter... >I open another door, and say, Had you selected door y, you would have won a dead catfish. Had he said: "I intentionally pick a door that is a loser and say..." THEN the solution being discussed is indeed valid. It his use of the knowledge he has that is the issue. If the host flips a coin, and uses the result of the coin toss to pick one of the other doors, then you are back to 50/50. He is not telling you anything, he is just eliminating a door, that just happens to be a loser. John W.
