The Middle School Math Probability Quiz is a free web app for practicing probabilities in a 4-choice quiz format.
Students can review probability basics, coins, dice, cards, balls, tree diagrams, complements, conditional probability, and entrance exam-style problems.
The course lineup starts with simple favorable/total questions and gradually builds toward multi-step probability and entrance exam practice.
Each question gives immediate feedback, and dynamic hints explain the next step with fractions, tables, tree diagrams, complements, and simple SVG visuals.
The app is useful for daily review, regular test preparation, and high school entrance exam practice.
Ranking, challenge history, best records, and often missed questions are saved so students can keep improving.
