Lesson 3: Independent and Dependent Events

Focus

There are many factors that can affect the outcome of a sporting event; because of this, specific rules are written for each sport. Home court advantage, travel distance, crowd size, and weather conditions are a few factors that may impact a team winning or losing.

• determine if events are independent or dependent

• calculate the probability of two dependent or two independent events

Lesson Question

You will investigate the following question: How are problems that involve the probability of two independent or dependent events solved?
