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 expressed as | A ∪ B | = | A | + | B | − | A ∩ B |, {\displaystyle |A\cup B|=|A|+|B|-|A\cap B|,} where A and B are two finite sets and |S| indicates the cardinality of a set S.
