Numberphile: Explaining the Monty Hall Problem

The “Monty Hall” problem is a common statistical question based on a game seen in the TV game show Let’s Make a Deal and the answer often seems to go against common sense. And, despite how many times we’ve seen the statistics behind the problem explained and demonstrated in the real world we still find it to go against our instincts. The math whizzes at Numberphile try their hand at explaining the problem and why the correct move isn’t the one that seems obvious.

If you’re still confused — and apparently a number of people who saw the video are — Numberphile tries to explain it in another way below.
