Inclusion-exclusion principle probability
WebThe Inclusion-Exclusion Principle (for two events) For two events A, B in a probability space: P(A ∪ B) = P(A) + P(B) – P(A ∩ B) Don't use this to “prove” Kolmogorov's Axioms!!! WebBoole's inequality, Bonferroni inequalities Boole's inequality (or the union bound ) states that for any at most countable collection of events, the probability that at least one of the events happens is no greater than the sum of the probabilities of the events in the collection.

This is the limit of the probability that a randomly selected permutation of a large number of objects is a derangement. The inclusion exclusion principle forms the basis of algorithms for a number of NP-hard graph partitioning problems, such as graph coloring. A well known application of the principle is the construction of the chromatic polynomial of a graph.
