7th Grade Math Chapter 13 Review Challenge

This video is a review session for seventh graders on Chapter 13, focusing on probability. It covers theoretical probability with simple events, compound events, and tree diagrams. Students practice calculating probabilities using examples like candy selection, clothing choices, and video game scenarios. The video also explores predicting outcomes using probability, such as rolling a number cube, predicting rain, and winning a track race. Students are encouraged to review their notes and videos if they need more practice.
