Outcomes

In this lesson you will

• Given two events A and B, use Venn diagrams to develop a formula for calculating the probability of A or B occurring. That is, you will develop a formula for P(A or B).

By the end of this section you should be able to:

• Demonstrate an understanding of the Fundamental Counting Principle and apply it to calculate probabilities of dependent and independent events.
• Determine conditional probability.
• Apply area diagrams and tree diagrams to interpret and determine probabilities of dependent and independent events.

Prerequisites

To be successful in this lesson, it would be helpful to know the following:

• How to use Venn diagrams.
• The mathematical meaning of the operators "AND" and "OR".
