Introduction. The U.S. Constitution established Americaâs national government and fundamental laws, and guaranteed certain basic rights for its citizens.

Under Americaâs first governing document, the Articles of Confederation, the national government was weak and states operated like independent countries.

Definition of Mutually Exclusive Events. Two or more events are said to be mutually exclusive if they cannot occur at the same time. In other words, events that have no outcomes in common are said to be mutually exclusive events or disjoint events. If two events A and B are mutually exclusive, then the probability of the occurrence of A or B is the sum of the their individual probabilities.
