What are the 4 rules of probability?

The Four Probability Rules

P(A or B)=P(A)+P(B)−P(A and B) In set notation, this can be written as P(A∪B)=P(A)+P(B)−P(A∩B). Whenever an event is the complement of another event, the Complementary Rule will apply. Specifically, if A is an event, then we have the following rule.
