The Monty Hall problem is a counter-intuitive statistics puzzle:

•There are 3 doors, behind which are two goats and a car.

•You pick a door (call it door 1). You’re hoping for the car of course.

Monty Hall, the game show host, examines the other doors (2 & 3) and always opens one of them with a goat (Both doors might have goats; he’ll randomly pick one to open)



Here’s the game: Do you stick with door 1 (original guess) or switch to the other unopened door? Does it matter? Surprisingly, the odds aren’t 50-50. If you switch doors, you’ll win 2/3 times!



Today let’s get an intuition for why a simple game could be so baffling. The game is really about re-evaluating your decisions as new information emerges.
