The addition rule states the probability of two events is the sum of the probability that either will happen minus the probability that both will happen. Learning Objectives Calculate the probability of an event using the addition rule Key Takeaways Key Points The addition rule is: P(A∪B)=...
" provided that we know the probability ofAand the probability ofB. Sometimes the "or" is replaced by U, the symbol from set theory that denotes theunionof two sets. The precise addition rule to use is dependent upon whether eventAand eventBare ...
1.2. Complementary probability The probability of the complement of event E (denoted as E’) is the probability that E does not occur: P(E') = 1 - P(E) 1.3. Addition rule for mutually exclusive events: If two events E1 and E2 are mutually exclusive (they cannot both occur simultaneou...

The general probability addition rule for the union of two events states that P(A∪B)=P(A)+P(B)−P(A∩B)P(A∪B)=P(A)+P(B)−P(A∩B), where A∩BA∩B is the intersection of the two sets. The addition rule can be shortened if the sets are disjoint: P(A∪B)=P(...
