Bad gums may mean a bad heart. Researchers discovered that 77% of people who have suffered a heart attack had periodontal disease, an inflammation of the gums. Only 34% of healthy people have this disease. Suppose that in a certain community heart attacks are quite rare, occurring with only 11% probability. A. If someone has periodontal disease, what is the probability that he or she will have a heart attack? Probability = B. If 37% of the people in a community will have a heart attack, what is the probability that a person with periodontal disease will have a heart attack? Probability
