This example demonstrates how coin-toss outcomes change under repeated trials by visualizing the evolving frequencies and the resulting empirical distribution. It focuses on key probability & statistics ideas: random experiments, sample frequency, and how an empirical distribution (Bernoulli-like outcomes) can be observed through repeated simulation. Construction-wise, GeoGebra uses Random to generate coin results, Element to build and manage the results list, Frequency to count occurrences, and Histogram to display those counts as a chart. TableText is used to present summary statistics in a table, while controls such as buttons and the parameter n (number of trials) update the simulation and graphics dynamically. Suitable for middle/high school probability lessons and for exploratory activities on “frequency tends to stabilize with larger samples.”

AI Drawing Prompt Reference

Create a dynamic statistical chart simulating coin-toss probability. The main graphic is a histogram with two bins (heads and tails) on the x-axis and relative frequency on the y-axis, where bar heights update with each trial. Beside it, a table displays the number of trials, counts for heads and tails, and their frequencies. Include a slider or input field to adjust the number of trials (n) and a button to restart the simulation. Each click generates a new random sequence of coin outcomes, updating the histogram and table in real time, illustrating how frequencies stabilize around 0.5 as n increases.
