Lets make a deal
here is something to debate:
Suppose you're on a game show and you're given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what's behind the doors, opens another door, say No. 3, which has a goat. He then says to you, "Do you want to pick door No. 2?" Is it to your advantage to switch your choice? Most will say, it is 50-50, but it is not. Resolving never to switch is equivalent to not having the option to switch, in which case, the odds of winning remain one in three. Switching, therefore, has a two-thirds chance at the prize. Onward with the debate!

It's that deja vu feeling all over again.

Re: Lets make a deal
Message to OP: sorry, I was feeling a bit frisky last night. Rereading this thread this morning, I realise you probably have no idea what I'm talking about.
Fact is, this problem has been debated at some length a number of times. I believe it's called the Monty Hall problem. Is Monty Hall a gameshow host? (I'm from the UK, so excuse my ignorance on such matters.) Anyway, if you use the search feature, you'll probably find the previous discussions. Apologies for not explaining myself better to start with.
