If n = 0 or n = 1, ( 2) gives a probability of 0.

WebPrinciple of Inclusion and Exclusion is an approach which derives the method of finding the number of elements in the union of two finite sets. This is used for solving combinations and probability problems when it is necessary to find a counting method, which makes sure that an object is not counted twice. Consider two finite sets A and B.
