Let's Make a Deal
This probability game is an electronic version of the old TV game show "Let's Make a Deal" which was hosted by Monty Hall.
Behind one of the doors is a grand prize and the other two doors lead to some real losers. To play the game select a door by clicking on it. "Monty" then reveals what is behind one of the two doors that you didn't choose. You are then given the option to stick with your original selection or switch to the other door.
The game can be played repeatedly with the results updated on the scoreboard. Try experimenting with the two strategies and decide which one is best.
Clicking on the Strategy button will lead to a series of questions whose answers will help explain the probability of winning with each strategy.
To play a large number of games in a row, Click on the Multiple Games button, select a strategy, enter the number of games, and press the Go button.
