# 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.

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
a^2 = sqrt(b^2 + c^2)
(See more on ASCIIMath syntax); or
2. Use simple LaTeX in the following format. Surround your math with $$ and $$.
$$\int g dx = \sqrt{\frac{a}{b}}$$
(This is standard simple LaTeX.)

NOTE: You can mix both types of math entry in your comment.
