Probability Tree & Venn Diagrams Interactive Demo

This GeoGebra example simultaneously presents a probability tree and a Venn diagram to visually illustrate random events and their probability relationships. Core mathematical concepts include conditional probability, event intersections, unions, complements, and the multiplication and addition rules of probability. Construction highlights: the summary lists numerous image objects (pic1 through pic16) serving as graphical elements, along with text objects (text1 to text5) for labeling probabilities, and variables a, b, c, d, e controlling dynamic parameters—likely via sliders or input fields—to update tree branches and Venn regions interactively. Suitable for high school probability and statistics instruction, helping students grasp abstract concepts, and also useful for introductory college statistics courses.
