In this lesson, we will learn how to tackle conditional probability word problems. Prior knowledge of how to draw tree diagrams is essential to this lesson.

In this lesson, we will interpret two-way tables and find conditional probabilities from them.

In this lesson, we will interpret Venn diagrams with two sets and find probabilities, including conditional probabilities from them, using the correct set notation.

In this lesson, we will interpret Venn diagrams with three sets and find probabilities, including conditional probabilities from them, using the correct set notation.
