Aha! This is the first explanation that reveals the most common error. The fact that the reveal isn't just a random door. The host must not reveal the car. That changes everything. I believe that's what most people are missing. But if you actually stated that explicitly, you would give away the answer and the problem wouldn't be fun anymore.
The fun is in not explicitly stating every unconscious assumption you have about the problem.

- munificent 3y agoYou would be surprised how many people do correctly understand the problem (that the host must open a door and must not reveal the car) but still get the resulting probability wrong.
