Apply and interpret the Addition Rule P(A or B)=P(A)+P(B)-P(A and B).
Find the probability that neither event occurs using the Addition Rule and the complement
Problem
The event that neither \(A\) nor \(B\) occurs is the complement of \(A~\text{or}~B\). Calculate \(1-0.72\).
Big Picture
What this problem is really about
Neither event means the complement of their inclusive union. We’ll translate the wording into that complement, subtract the known union probability from one, convert the remainder to a percent, and check that the event and its complement sum to the full probability.
