Conditional Probability and Bayes's Theorem Applet

Click on the solid rectangle in the middle of the cross hairs to change the probabilities of each of the events in the partition A1, A2, A3, A4. You can see the effect of these changes on the conditional probabilities and the Bayes results shown at the bottom of the applet.

(If you are viewing this from behind a firewall, chances are that your webmaster has configured your security so that JAVA functions only on your intranet, and not across the web. So right now you are looking at a gray square, or maybe not even that, which isn't nearly as entertaining as the actual applet.)

You can find out more about conditional probability and other statistical learning exercises at West's website.
