Creating Tree Diagrams to find Theoretical Probability

We are learning to…find the theoretical probability of an event.

Page 2: Creating Tree Diagrams to find Theoretical Probability

Vocabulary

Theoretical Probability - Probability that is based on likelihood of an event happening based on all the possible outcomes. One way to determine theoretical probability

is to build a TREE DIAGRAM A Tree Diagram is a way to visually

represent and organize all the possible outcomes of an experiment.
