Understanding Basic Probability Concepts

This video tutorial covers basic probability rules, focusing on creating probability models and understanding sample spaces. It explains how to calculate event probabilities using these models and introduces key probability rules, including the complement rule and the addition rule for mutually exclusive events. The tutorial uses examples like rolling dice and selecting M&Ms to illustrate these concepts, ensuring learners can apply these rules to real-world scenarios.

What is the complement rule in probability?

• The probability of an event occurring is the same as it not occurring

• The probability of an event not occurring is one minus the probability of it occurring

• The probability of an event is always between 0 and 1

• The probability of two events occurring together is zero
