Let 
be the set of n mutually exclusive and exhaustive events whose union is the random sample space S, of an experiment.
If A be any arbitrary event of the sample space of the above experiment with P(A) ≠0, then
the probability of the event 
when event A has actually occurred is given by ,)
where
=\frac{P(E_{i})P(A/E_{i})}{P(E_{1})P(A/E_{1})+P(E_{2})P(A/E_{2})+....+P(E_{n})P(A/E_{n})})
