A puzzle

[FlawlessHappiness]

You have one choice.

This is a lie. The showmaster clearly gives me another choice after picking 1 door out of 3.

If I stay at my first choice, the door that was revealed empty, then I have a 0% chance of getting the car.

If I choose another door I have a 50% chance to get the car.


Which would I pick, you ask? The one where I have a chance of course.



Then another candidate comes in. He has the same conditions as me when I picked a door among 3.

You ask whether he has the same chance than I had. But I had 2 picks where he only has 1.

If we compare it to my first pick, then yes. We both had 33% chance.
If we compare it to my second pick, then no. I have 50% chance, and he only has 33%.
