e two mutually exclusive events
having nonzero probabilities of occurrence can not be independent (iii)
Two experiments are said to be independent if for every pair of events E and F,
where E is associated with the first experiment and F with the second experiment,
the probability of the simultaneous occurrence of the events E and F when the
two experiments are performed is the product of P(E) and P(F) calculated
separately on the basis of two experiments, i e
