Recently, i wrote a bayesian formulation of carl sagan’s famous maxim, ‘extraordinary claims require extraordinary evidence’however, since the aim of that post was not to teach bayes’ theorem, but to reply to a criticism of the maxim, i may have left readers unprepared to actually use this theorem.
