        This is worded better than what I said. The second round isn’t 1/2 because the door you initially picked was 1/100.

      Only if Monty Hall didn’t know where the prize is

      Say there are 100 doors, you choose one, then 98 are knocked out randomly (likely including the prize) - Now each of the 2 doors has the same chance of winning, so there is no reason to change

      But starting with 100 doors and a knowledgeable Monty Hall, once you’ve chosen a door, the only reason Monty Hall leaves your door alone is because you chose it, whether it is the 1/100 winner, or one of the 99/100 losers

      Either you chose the right door the first time (1/100 chance) or the other door has the prize behind it - those are the only options - the other door literally represents the 99/100 other doors in a single choice

        There’s a flaw in this problem, which is the fact Monty Hall didn’t consider the possibility I may have a gun pointed to his head
