then tough one

there are two answers to this problem.

ifit is a trick question, the fact that you said "a goat" would imply one goat, which if already revealed would mean your options are better. but if there was a goat behind the door you opened (not specified) then your odds would be 100% that the third door would hold a BMW, since both goats would be revealed.

so that argument is all semantics.

Say the door you opened was goatless, then it comes down to odds.

the mathematical approach is you started with 66% odds of failure to start. eliminating one goat would mean your odds drop to 50% of failure, or a coin flip.

at least thats my take
