Solving the Monty Hall Problem (an Infographic)

I’ve been in the mood lately to do something “creative” and thought working on an infographic might be fun. I was going to make a graphic showing the price increase of SXSW tickets over the past 15 years, but I lost interest after gathering much of the data. Then I was listening to the Security Now podcast on the TWiT network where Steve Gibson and Leo Laporte were talking about the Monty Hall Problem. If you’re unfamiliar with the Monty Hall Problem it comes from the old game show, Let’s Make a Deal where Monty Hall gives a contestant a choice of three doors: Behind one door is a car; behind the others, goats. The contestant picks a door, say number 1 (but the door is not opened), and Monty, who knows what’s behind the doors, opens another door, say number 2, which has a goat. He then asks the contestant if they want to stick with their original choice or switch to door number three.

The Monty Hall Problem is the question, “Is it to your advantage to switch your choice?”
