Exploring Compound Probability Concepts

The video tutorial covers compound probability, explaining how to calculate the probability of two or more events occurring. It introduces tree diagrams as a visual tool to organize and calculate probabilities. The tutorial also discusses the concepts of probability with and without replacement, highlighting the differences between independent and dependent events. Practical examples are provided to reinforce the concepts, and the importance of practice is emphasized.

What is compound probability?

• Probability of a single event occurring

• Probability of two or more events occurring together

• Probability of an event not occurring

• Probability of an event occurring in the past
