Let's Make A Deal: This is a strategy games where you pick one of three doors. Upon picking a door one of the other two doors are opened (a loser). You must then decide if you would prefer to stick to your original decision or change to the other door. I played 20 games where I changed my initial decisions and the results were that I won 13 games or 65% and lost 7 games 35% and then I played another 20 games where I stuck with my initial choice. The results from this strategy were I won 5 games 25% and lost 15 games 75%. This was another great game that would keep my students interest and provide a lesson on probabilities.
