This example demonstrates through a dynamic tree diagram that a tree diagram is not always a useful tool in all situations. It involves the concept of tree diagrams in probability and statistics, and uses commands such as Intersect, Random, If, Segment, and Textfield to construct the dynamic tree diagram. Suitable for middle school and above students to learn probability and statistics.
