Roll Die Simulation: Random Number and Frequency Distribution

① This GeoGebra example simulates rolling a die, dynamically showing each outcome and the evolving frequency distribution of the six faces. ② Core mathematical concepts include random events, empirical frequency versus theoretical probability, frequency distribution histograms, and integer random number generation. ③ Construction highlights: the Random command generates random integers, the object Roll stores each result, and six image objects (pic1 to pic6) correspond to the six die faces for visual feedback; frequency statistics and curve sketching tools illustrate how frequencies approach the theoretical probability (1/6) as trials increase. ④ Suitable for middle school probability and statistics lessons, as well as introductory college statistics courses, to demonstrate the law of large numbers and the balance between randomness and regularity.
