Probability Concepts and Problems

This video tutorial introduces Grade 11 students to probability, focusing on tree diagrams and compound events. It explains how to use tree diagrams to calculate the probability of compound events, such as drawing balls from boxes or tossing coins. The tutorial provides examples, including calculating probabilities for different outcomes using tree diagrams. It concludes with a summary and directs students to additional resources for further learning.

What is a compound event in probability?

• An event that cannot occur

• An event with no possible outcomes

• An event with multiple outcomes

• An event with a single outcome
