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.

 

Can you think of factors that have no bearing on the outcome of a game? In this lesson you will discover that there are some events that directly affect each other and others that are strictly independent.

 

Lesson Outcomes

 

At the end of this lesson, you will be able to

  • determine if events are independent or dependent
  • calculate the conditional probability of one event
  • 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?
