This applet is written to accompany the Multiple Birthdays Problem by Louie Beuschlein. His problem asks what is the probability of two or more duplicated birthdays within a group of people. Click on the above link to read his explanation.
This applet allows you to choose the number of people in a group. It then runs the simulation as many times as you enter for trials by randomly selecting birthdays for each of the people in your group. It tells you the percentage of your trials that resulted in exactly one duplicated birthday, atleast one duplicated birthday, and atleast two duplicated birthdays (the main problem). The mathematical probability for atleast two duplicated birthdays is shown last. This probability is calculated using the final equation in Louie Beuschlein's explanation.
Choose the number of people in your group, select the number of trials that you'd like to run, and click "Find Probabilities"!
