      Union: The union of two events consists of all outcomes that are either in the one event and/or in the other event. Say one event is even {2, 4, 6} and the other is “greater than 3” of {4, 5, 6} then the union would be all the possible outcomes of both, but do NOT repeat an outcome! Thus the union sample space would be {2, 4, 5, 6} Notice ...

      Mutually Exclusive Events. Two events A and B are mutually exclusive or disjoint if , that is if A and B have no common elements in common. The Union of Events. The union of two events A and B, denoted by the symbol is the event containing all elements that belong to A or B or both. Important Notes.
