WebOct 12, 2015 · One essential aspect of the Inclusion-Exclusion Principle (IEP) is the transformation of at least information to exact information. If counting objects having at least a number of properties is simple, but counting objects having exactly a number of properties is difficult, than the IEP comes into play.
