This simple game is to showcase the Monty Hall / Let's Make A Deal probability problem.
The game starts with 3 closed doors, 2 of them have goats behind them and the other a car. You pick a door and then Monty shows you one door with a goat behind it, now you have a choice to stay with your choice or switch doors.
Which is better to do?
