Prompt
You're on a game show and are presented with three doors. Behind one is a donkey, and behind the other two are luxury cars. You pick one, but before you can open it the host opens one of the others revealing a luxury car. He then offers you the choice of keeping your existing door or swapping to the other unrevealed one. What should you do to win a car?

How to grade it

Keep your original door. Your first pick is a car with probability 2/3; if you picked a car, the other unopened door hides the donkey, so switching wins only 1/3 of the time (standard assumption: the host knowingly reveals a car).

Answer check: Enumerated all three donkey positions: staying wins in 2 of 3.

Scorecard tick what the model got right: 0/4

Where models usually fail

Reciting 'always switch, 2/3' from the classic problem, which here maximises the chance of getting the donkey.
