When Math Betrays Your Gut
Probability is one of the few areas of mathematics where brilliant people — including PhDs — routinely get the wrong answer. The Monty Hall problem, Birthday Paradox, Gambler's Fallacy, and Bayes' Theorem all produce results that feel deeply wrong the first time you encounter them. Work through 5 famous counterintuitive probability problems, pick your best guess, and then read the mathematical explanation to see exactly why the intuitive answer fails.
