Bayes' rule is a fundamental theorem in probability theory and statistics that allows for the updating of probabilities given new evidence. It is used to update prior probabilities to posterior probabilities after observing new information, effectively "turning around" conditional probabilities to assess the likelihood of various hypotheses given observed evidence. Thus, all the listed options are correct applications of Bayes' rule.
