Virtual Nerd: How Do You Use a Tree Diagram to Count the Number of Outcomes

Cultivate the tree of knowledge using diagrams with two stages. Pupils create small tree diagrams to determine the sample space in compound probability problems. The lesson uses only two decision points to introduce tree diagrams.
