This results in the inclusion of the same term more than once; hence we use the inclusion-exclusion principle. Clearly, in set theory, the union of two sets A and B can be represented as :

Web1 Principle of inclusion and exclusion Very often, we need to calculate the number of elements in the union of certain sets. Assuming that we know the sizes of these sets, and their mutual intersections, the principle of inclusion and exclusion allows us to do exactly that. Suppose that you have two setsA;B. WebApr 9, 2016 · How are we going to apply the inclusion-exclusion principle ? For a positive integer $n$, whenever you divide $n$ by one of its prime factors $p$, you obtain then number of positive integers $\le n$ which are a multiple of $p$, so all of these numbers are not coprime with $n$.
