7.2: The Inclusion-Exclusion Formula - Mathematics LibreTexts

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. The inclusion exclusion principle forms the basis of algorithms for a number of NP-hard graph partitioning problems, such as graph coloring. A well known application of the principle is the construction of the chromatic polynomial of a graph. Bipartite graph perfect matchings See more In combinatorics, a branch of mathematics, the inclusion–exclusion principle is a counting technique which generalizes the familiar method of obtaining the number of elements in the union of two finite sets; symbolically … See more Counting integers As a simple example of the use of the principle of inclusion–exclusion, consider the question: How many integers in {1, …, 100} are not divisible by 2, 3 or 5?
