### AI overview

A mathematically rigorous primer on conditional probability. It reviews finite probability spaces, probability mass functions, events, random variables, and partitions as tools for decomposing events and variables and reasoning about total probability.

### Source excerpt

One of the main areas of difficulty in elementary probability, and one that requires the highest levels of scrutiny and rigor, is conditional probability. The ideas are simple enough: that we assign probabilities relative to the occurrence of some event. But shrewd applications of conditional probability (and in particular, efficient ways to compute conditional probability) are key to successful applications of this subject. This is the basis for Nate Silver's success, the logical flaws of many a political pundit, and the ability for a robot to tell where it is in an environment.
