Using Tree Diagrams Representing a Sample Space to Calculate Probabilities

EngageNY 45 min(s)

Given a description of a chance experiment that can be thought of as being performed in two or more stages, students use tree diagrams to organize and represent the outcomes in the sample space. The tree diagram is a particularly useful device when the experiment can be thought of as occurring in stages. When the information about probabilities associated with each branch is included, the tree diagram facilitates the computation of the probabilities of the different possible outcomes.
