What you’ll learn

  1. You'll understand the classic game show scenario: three doors, one prize, and why your initial choice has only a 1/3 chance of being correct.

  2. You'll discover that switching doors after the host reveals a losing option doubles your winning probability from 1/3 to 2/3.

  3. You'll learn how the host's knowledge changes the odds: when the host deliberately reveals a losing door, it shifts the probability landscape in your favor.

  4. You'll apply the switching principle to relatable scenarios — from job offers to checkout lines — and recognize when an expert's elimination of an option should change your mind.
