Inclusion exclusion probability
WebIn a probability space (W,F,P), interpretation of the events as sets allows us to talk about the intersection and union of the events. Intersection and unions are useful to assess the probability of two events occurring ... The inclusion-exclusion identity holds not only for a probability measure but also for a counting (cardinality of a set ... WebProve the following inclusion-exclusion formula P ( ⋃ i = 1 n A i) = ∑ k = 1 n ∑ J ⊂ { 1,..., n }; J = k ( − 1) k + 1 P ( ⋂ i ∈ J A i) I am trying to prove this formula by induction; for n = 2, let A, B be two events in F. We can write A = ( A ∖ B) ∪ ( A ∩ B), B = ( B ∖ A) ∪ ( A ∩ B), since these are disjoint unions, then
