WebThe rule for OR must take into account values that may get counted more than once where the sets overlap. In the first version, this overlap is dealt with when finding n(A or B). In the second version, this overlap is dealt with in the subtraction of the intersection, P(A and B). If sets A and B are mutually exclusive (no elements in common), P(A and B) = 0, WebProbability tells us how often some event will happen after many repeated trials.
