The extreme example to prove this is the one I offered early on in this thread, having 100 doors instead of 3 doors, and Monty, with his knowledge of which door contains the car, opens 98 other doors with the goat behind all of them. leaving only your door and one other door. Do you still think you have a 50-50 chance at this point? You actually have a 1 in 100 chance. Anyone that can’t understand this is just plain stubborn, ignorant or both.
That's a really good explanation.
