Similarly, two random variables are independent if the realization of one does not affect the probability distribution of the other . </P> <P> The concept of independence extends to dealing with collections of more than two events or random variables, in which case the events are pairwise independent if each pair are independent of each other, and the events are mutually independent if each event is independent of each other combination of events . </P>

What does it mean if 2 events are independent
