The sample space, an event, and the probability of an event; Exclusivity and independence (both are different) 2. Finally, a third axiom (the same one used in the second step of filling in the Venn diagram) asserts the probability of equals the sum of the probabilities of its four parts, because they are disjoint. 1.
