The door switch
You picked a door and the host opened the others, showing goats. Should you switch, and does it matter whether he knew?
A game show with one car and a row of doors, played three thousand times. You pick, the host opens every door but yours and one other, and offers the swap. The panels count how often staying and switching win. Watch what happens when the host stops knowing where the car is.
Board: Monty Hall, the Illegal Switch →On a narrow screen the three panels stack below the controls, and the table scrolls sideways.
try this Drag How many doors, then press Host guesses, and watch the percentage under Switching wins.
