Khan Academy volunteer Peter Collingridge has created a computer science simulation that demonstrates what happens when you play “Let’s Make a Deal” with Monty Hall and have to choose what’s behind door number one, two, or three.

Watch the simulation here:

Peter’s simulation illustrates Sal’s lesson that it makes sense to change your initial pick after Monty reveals to you that one of doors you didn’t pick has a goat behind it instead of a car.
