If you simply mean that there are two choices - one correct, one incorrect - then you are right
That is what I meant....

I'll reword it to:

Although there are two choices in the final decision....the probability odds are not a true 50/50 but 33/66 (stay/switch).

This article refers to another exhibiting the same principle in the game of bridge: restricted choice. This is the setting in which I first encountered the principle.

edited because programers are never right the first time.
I increased the loop to 10000000. After a couple runs the numbers seem to be too close.

ok math minor here(comp sci major ), and i dont see how there is any advantage either way.

http://mathforum.org/dr.math/faq/faq.monty.hall.html

This website claims that there are only three possible methods of choosing. This is incorrect. There are four, which again makes the ratio 2/4.

If you read the article it says that there are three different ways of going about the problem. If you read carfully the first method describes Monty as chosing "A or B" which should be seperated into seperate methods.
