Combinatorics Visualizer

Explores counting methods and the rules of probability for compound events and discrete random variables. Combinatorics Visualizer turns that idea into something you can manipulate directly and watch respond.

Explores counting methods and the rules of probability for compound events and discrete random variables. It focuses on Permutations and combinations, Addition and multiplication rules, Discrete probability distributions, Expected value from the “Probability and Combinatorics” section.

The “Total Items (n): 5”, “Sample Size (r): 3”, “Mode” sliders change the key inputs; the “Permutations”, “Combinations” buttons run actions or reset the demo. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.

The Client Challenge Precalculus course is a comprehensive curriculum designed to bridge the gap between high school algebra and college-level calculus. It covers ten core units ranging from composite functions and trig… This demo is the interactive piece for the “Probability and Combinatorics” section.

You'll build intuition for Permutations and combinations, Addition and multiplication rules, Discrete probability distributions, Expected value — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on Precalculus alone.
