Exploring Probability Concepts for Grade 7

This video tutorial provides a comprehensive review of probability concepts for grade seven students. It covers outcomes and events, describes probability terms, and explains both experimental and theoretical probability. The tutorial also introduces the fundamental counting principle and compound probability, using practical examples like marble selection to illustrate these concepts. Students are encouraged to pause and solve tasks independently before reviewing the solutions.
