   Bayes' theorem (alternatively Bayes' law or Bayes' rule, after Thomas Bayes) gives a mathematical rule for inverting conditional probabilities, allowing us to find the probability of a cause given its effect. [ 1] For example, if the risk of developing health problems is known to increase with age, Bayes' theorem allows the risk to an ...
