You've got a choice here... you can either interpret "The probabilities change" as meaning the probabilities of a given door being correct at the start (which would be a misunderstanding) or you could interpret it from the pragmatic angle; the probability of success if you switch doors after one is taken away.
Given the context I'm inclined to believe that wrsh07 intended the latter.
