Bayes' Rule

Captions available

The idea

Bayes' rule computes updated belief from three quantities: how probable the evidence is if the claim holds, the prior, and how probable the evidence is overall.

In practice

Posterior equals likelihood times prior, divided by the evidence's total probability — the counting method, compressed to a formula.

Where people slip

The count comes first on purpose: whoever owns the counting can rebuild the formula from a napkin.
