FunctionCoordinate GeometryProbability & Statistics
This example demonstrates counting rules in combinatorics, including permutations, combinations, ordered with replacement, and unordered with replacement. By inputting the number of items n and the number of choices r, it dynamically shows the results of different counting rules. It uses TextField, InputBox, and Text objects in GeoGebra. Suitable for high school math education and learning.

GeoGebra Commands & Parameters

  1. Textfield(n) → InputBox1
  2. Textfield(r) → InputBox2

AI Drawing Prompt Reference

Create an interactive educational diagram illustrating counting rules in combinatorics. Place two input boxes in the center, one for the total number of items and one for the number of choices. Below or beside them, dynamically display four counting results: permutations, combinations, ordered with replacement, and unordered with replacement. Each result appears as clear text with a brief formula or description. The layout is clean and suitable for high school classroom demonstration, emphasizing comparisons and relationships among different counting rules.
