Being able to calculate and interpret probabilities is important. Be sure to understand how to interpret venn diagrams, two way tables, and tree diagrams.
A **two way table **or **venn diagram **can be used to display the sample space and to help find probabilities for a chance process involving two events. A **tree diagram **shows the sample space of a chance process involving multiple stages. The probability of each outcome is shown on the corresponding branch of the tree. All probabilities after the first stage are *conditional probabilities. *

A **venn diagram** consists of one or more circles surrounded by a rectangle. Each circle inside the rectangle represents the sample space of the chance process.
