Rectangle and Random Variables Interaction Demo

This example demonstrates the dynamic interaction between rectangles and random variables. It involves core mathematical concepts such as rectangle construction, random variable generation, multiplication, sequences and series, and linear functions. The construction uses GeoGebra commands like objects A, B, text1, C, D, pic2, text2 to build and display graphical and textual elements. Suitable for high school and above mathematics education, focusing on the application of probability statistics and linear functions.
