## What it is
A comprehensive 10-page probability cheatsheet in LaTeX/PDF form, compiled from Harvard's Stat 110 introductory probability course by William Chen and Joe Blitzstein. It summarizes key probability concepts, formulas, distributions, and problem-solving strategies with figures and examples.

## Use cases
- probability formulas reference sheet
- study guide for intro probability course
- quick reference for distributions and random variables
- exam prep for statistics class
- probability cheat sheet pdf download
- learn probability concepts quickly

## When to choose
- you need a compact reference for introductory probability topics like distributions, expectations, and Markov chains
- you are studying Harvard Stat 110 or a similar intro probability course
- you want a printable formula sheet with worked examples and figures

## When to avoid
- you need rigorous full-length textbook treatment rather than a summary
- you need measure-theoretic or advanced graduate probability
- you require an open-source license permitting commercial use (it is CC BY-NC-SA)
