Probability Tree & Venn Diagrams Interactive Demo by sakhanh

① This GeoGebra example dynamically illustrates the construction and interconnection of probability tree diagrams and Venn diagrams, enabling learners to intuitively grasp random events and their probability relationships. ② Core mathematical concepts include probability calculation, conditional probability, event intersection and union, expected value, arithmetic mean, and probability distributions over real numbers. ③ Construction highlights: from the summary, numerous image objects (pic1 to pic16) serve as graphical elements, text objects (text1 to text5) label probability values, and variables a, b, c, d, e control parameters for different branches or regions, allowing dynamic adjustment via sliders or input fields. ④ Suitable for middle school (introductory probability) through high school probability and statistics, as well as basic university probability courses; ideal for classroom demonstrations or student self-exploration of the relationship between tree diagrams and Venn diagrams.
