This interactive Flash applet allows students to understand the distribution of sums that result when rolling two dice. By experimenting with different numbers of rolls, they see how increasing or decreasing the number of rolls affects the outcome. After virtually rolling the requested number of times, the applet displays the result of each roll as well as a bar graph of the distribution. A link to introductory information on probability is included.
