START WITH A QUESTION

Curious about a probability puzzle? Each one links to an interactive tool or explainer.

→What are the odds two people in a room share a birthday?→Why does roulette always favor the house?→What does a positive medical test really mean?→How many coin flips until randomness looks predictable?→What is expected value in real decisions?→Is a lottery ticket ever mathematically worth it?

Built for learning, not betting. The Probability Lab is for mathematical curiosity and education, simulations illustrate probability, expected value, and long-run behavior, and are not gambling advice.

Methodology

All simulations use the Web Crypto API for true randomness, not pseudo-random Math.random().

Data

Results are stored anonymously via session ID. No personal data collected.

Purpose

This is a probability and statistics education tool. All outcomes are pure math.
