Interactive tools

Playground Expected Value Lab Define each outcome of a chance situation — value and probability — and watch E(X) compute live. Try the carnival, lottery, and insurance presets to see why every gambling operation is engineered for a negative expected value to the player. Playground Law of Large Numbers Simulator Pick coin, die, or a custom probability, then run trials in batches of 10, 100, 1,000, or 10,000. Watch the experimental probability bounce around at low n and converge on the theoretical value as n grows — the Law of Large Numbers in real time.
