# Looking at Bayes’ Theorem 2

Quick followup to the previous post, now with an interactive SVG plot
(SVG is cool!). EDIT: For some reason, a combination of wordpress and both Safari and Firefox dislike my SVG. Click on the link above or the image below to interact with the plot:

$P(A)$ is the probability that a person is a drug user, $P(B|\tilde{} A)$ is the false positive rate, $P(B|A)$ is the “true positive”, or coverage, and $P(A|B)$ is the
chance the person that tested positive actually did drugs (which is
what we were after)

This is my first shot at SVG, but it made me want to learn more about it. It seems like it
can be a treasure trove of cool hacks. Can SVG scripts do AJAX? If
so, how come no one has written a MMORPG 3D game with it? Oh, wait. Now for the AJAX.
