Monty Hall Simulation

The applet below serves a simulation of the Monty Hall Dilemma in the most straightforward manner. You select a door by clicking on it. After you make your first selection, the applet takes on Monty's responsibilities and opens a door to reveal a goat. You then need to click the second time, whether on your first selection or by choosing a different door. Actually it is not quite important what you do as the applet keeps four counts: SwitchedAndLost, StayedAndWon, SwitchedAndWon, StayedAndLost. The first two are always equal as are the second two. On you second click the remaining doors are open and the relevant counts change. You are able to verify whether you won a car or lost (= won a goat) on this trial. You need to click a third time to close the doors and prepare the applet for the next trial.

Pressing the Reset button initializes the counts.

(A time saving simulation is available elsewhere.)
