Comparing this to the Monty Hall problem:
Probability of choosing the correct door at time of choice:
Two Envelopes: 1/2 -> 1/2
Monty Hall: 1/3 -> 1/2
...because Monty opens one of the doors, providing information.
- devman0 4y agoMonty opening the door condenses the probabilities of the two unpicked doors in to the one unpicked door. This occurs because Monty only opens a door with a goat and never the car. In the original three door version you always had a 2/3 chance of winning if you switched because you'd only lose if you correctly picked the car on the original 1/3 pick.
