Additional question: It is known that 1/3 of the St. Catharines adult population does not accumulate enough physical activity to experience health benefits. Lack of physical activity is a risk factor for various health conditions including cardiovascular disease, cerebrovascular disease, and osteoporosis. If 10 adults are randomly selected from this population: a) What is the probability that exactly 8 of them will not be physically active? b) What is the probability that at least 9 will not be physically active?...

Problem 5. The U.S. Bureau of Labor Statistics reported that, as of 1981, approximately 21% of the adult population under age 65 was between 18 and 24 years of age, 28% was between 25 and 34, 19% was betwe enn 35 and 44, and 32% was between 45 and 64.
