# Friday math movie - NUMB3RS and Bayes’ Theorem

By Murray Bourne, 23 Nov 2007

There are 2 related videos for your viewing pleasure this week.

Here's Charlie (the main character in the NUMB3RS tv series) explaining the Monty Hall problem to his students. It has a good twist, of course. What you expect intuitively is not the best decision.

Here is another explanation of the same thing from Ron Clarke (which has a bit of a Monty Python feel):

## Baye's Theorem

Here's quite a good (if lengthy) explanation of Bayes' Theorem. From the page's intro:

... an excruciatingly gentle introduction.

There's a bunch of Java applets on that page that let you play with the concepts and investigate the meaning.

See the 4 Comments below.

Cool videos; I love the Monty Hall problem!

P.S. It should be “Bayes’ theorem”; it’s named after Thomas Bayes.
