Two doors can not have 66% chance because... because... 66 + 66 > 100. Go to the school already.

The things are easy:

3 closed doors: 33.3(3)% chance for each
2 closed doors: 50% chance for each
1 closed door: 100% chance

INITIALLY these two doors (actually ANY 2 of 3) together had a 66.6(6)% chance and any other one had 33.3(3)%, so summary it was 100% for 3. When one door was removed from the equation, the probability for the rest two doors has changed. Now it's 50% for each of them, so summary it's still 100%.

You don't have to be Einstein to understand the basics of probability theory. In Soviet Union we learned it in the school at 13-14 year old (7th grade). The makers of that movie are idiots and they make more idiots among those who watch this shit.
