In this activity, students experiment with different versions of the Monty Hall problem where the goal is to find a prize hidden behind one of three doors. You start by choosing one door without opening it then one of the other two doors that doesn't have the prize behind it is revealed. Then you are faced with the decision to "stay" with the first door you selected or "switch" to the other remaining door. The student has the option to play the game or run multiple trials at once in order to get a better idea of the overall probability of each strategy. Students can also adjust the number of doors they have to choose from. This activity allows students to explore conditional probability as well as bar graphs and trials. This activity includes supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the java applet.
