The formal addition rule expressed the probability of A or B as follows: P{A or B) = P{A) + (B) — P{A and B). The exclusive or means either one or the other events occurs, but not both. Rewrite the expression for P{A or B) assuming that the addition rule uses the exclusive or instead of the inclusive or. {Hint: Draw a Venn diagram.)
