Explore probability from coin flips to Bayesian inference with interactive simulations, distribution tools, and real-world applications.
Roll the DiceSimulate thousands of rolls and flips to compare experimental and theoretical probabilities.
Adjust parameters of common distributions and see PDF, CDF, mean, and variance update in real time.
Run Monte Carlo simulations to estimate probabilities for complex events and geometric probability.
Step through Bayesian updates with prior, likelihood, and posterior visualized as probability trees.
Master permutations, combinations, the multiplication principle, and probability axioms through visual counting exercises and tree diagrams.
Study discrete and continuous distributions — binomial, geometric, Poisson, normal, uniform — with interactive parameter explorers.
Apply Bayes' theorem, conditional probability, and independence to medical testing, quality control, and decision-making scenarios.
Running 10,000 dice simulations and watching the distribution form taught me the law of large numbers instantly.Prof. Adams, Probability
The Bayes calculator made conditional probability visual instead of just formulas on a page.Tanya P., Grade 12
