: If a task asks for the probability of rolling a "6" on a die, the student can click a button to "simulate 1,000 rolls". The app then instantly displays a frequency table and a bar chart of the results.

: Instead of revealing the whole solution at once, use "hint layers." A student can toggle "Show Formula," then "Show Calculation," and finally "See Simulation" to ensure they understand the why before getting the answer. Educational Value

To make a GDZ (Готовые домашние задания - Ready-made Homework Solutions) for the 7–9 grade "Probability Theory and Statistics" textbook more than just a list of answers, you can add a feature.

Instead of just showing the static solution to a problem about rolling dice or flipping coins, this feature provides an interactive sandbox where students can "verify" the math through their own experimentation.
