Probability primer 5 which is the form in which bayes’ rule is normally presented the probability of the data given the hypothesis, p(d|h), is known as the likelihood probability theory also allows us to compute the probability distribution associated. The probability of an event is its relative frequency (expected proportion) in the long run if an event if an event occurs x times out of n , then its probability will converge on x ÷ n as n becomes infinitely large.
