WebOct 12, 2015 · In lieu of a rigorous proof, it is easy to see that the IEP rests on the following principle: suppose that $x$ is a member of $n$ sets. Then $x$ gets counted $n$ times on the first count, subtracted $n$ choose $2$ times on the second count, added back in $n$ choose $3$ times on the third count, etc. In other words: 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.
