This project calculates the likelihood that three people in a room will have the same birthday. Use the slider to select the number of people in the room, and click the Green Flag to start.
Recently, my brother-in-law was at a meeting where three people had he same birthday. He asked me how unlikely this was. So I created this project to calculate the likelihood that three people in a room have the same birthday. (At my brother-in-law's meeting, there were 41 people. I ran this project to show that there is about a 7% chance that 3 out of 41 people would have the same birthday.)
