In a Canadian population, 54% of people are highly active (exercising 5 hours or more per week); 71% of people have no difficulty falling asleep within 30 min; and 17% of people are highly active and have trouble falling asleep within 30 min. If a person is randomly selected from the population who are not highly active (exercising less than 5 hours per week), what is the probability this person have no difficulty falling asleep within 30 min?
