To maintain their physical fitness, Americans are exercising more than ever in a variety of ways. Bradley and Robbins interviewed many Americans to determine how the were exercising. In How American Exercise, they present the
following: 53% jog, 44% swim, 46% cycle, 18% jog and swim, 15% swim and cycle, 17% jog and cycle, and 7% jog, swim, and
cycle. If an American who exercises regularly is randomly selected, what is the probability that the person either jogs,
swims or cycles to maintain physical fitness?
