## Thinking Mathematically (6th Edition)

a. On the graph, find the blue vertical bar corresponding to men, 25-34 (second from the left). Its height (read from the y-axis) is 0.1. If E is the given event, (a randomly selected man between the ages of 25 and 34 has cardiovascular disease), then P(E)=0.1 b. Apply Complement Rules of Probability, $P($not $E)=1-P(E) =1-0.1=0.9$
