A friend was recently at a Zoom workshop with 16 participants. Throughout the workshop, the participants were often divided into four breakout rooms, with four people in each. He wondered how likely it was for him to be in same breakout with his friend at some point during the workshop. I created this simulation to try to get a better understanding. Click the Green Flag to run one million trials of the workshop, and see when he first gets matched with his friend in a breakout session. I created this project to simulate this situation. Just click the Green Flag to run the simulation, over and over. (Want to make the simulation run faster? Hide the list monitors by clicking the "run faster" button.)
Thanks to Ken Loveday for posing this question.
