Inclusion-exclusion principle formula

WebTHE INCLUSION-EXCLUSION PRINCIPLE Peter Trapa November 2005 The inclusion-exclusion principle (like the pigeon-hole principle we studied last week) is simple to state and relatively easy to prove, and yet has rather spectacular applications. In class, for instance, we began with some examples that seemed hopelessly complicated.
