LOL... How do you figure that? Since initially you were choosing from 3 doors, behind which there are 2 goats and 1 car - therefore you have a 66-33 chance of having initially chosen the goat. It does not matter, that one of the goat-doors was opened afterwards - your chances of having picked a goat are the same.
