This app is a practical tool designed for teaching and data analysis. Users only need to enter the number of event occurrences and the total number of experiments to quickly calculate the experimental frequency and compare it with the set theoretical probability. The app provides a bar chart to visualize the difference, and supports exporting results as images or PDF files for easy report organization. The built-in history function can trace multiple calculation processes, and one-click recovery is convenient for teaching demonstrations and review. The interface is simple and suitable for middle school teaching, probability training and introductory data analysis.
