WebMay 12, 2024 · Inclusion-Exclusion Principle In case of two sets In many problems, we must include contributions of more than one term in our answer. 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 :
