On Wednesday the 7th Graders hosted a Probability Carnival in order to demonstrate their knowledge of simple probability. Each group had to design a game and then calculate the probability of a win. During the carnival students recorded the results of their classmates plays. The 6th grade, High School, and Upper School teachers had a great time playing the various games and winning prizes. It was a great chance to observe the difference between calculated probability and observed probability (as well as reflect on working together in groups, advertising, and quality construction of projects).
