Estimates of the prevalence of Alzheimer’s disease are given in Table below. Suppose an unrelated 77-year-old man, 76-year-old woman, and 82-year-old woman are selected from a community. Table 1 Prevalence of Alzheimer's disease (cases per 100 population) Age group Males Females 65-69 1.6 0.0 70-74 0.0 2.2 75-79 4.9 2.3 80-84 8.6 7.8 85+ 35.0 27.9 What is the probability that exactly one of the three people has Alzheimer’s disease? Suppose we know one of the three people has Alzheimer’s disease, but we don’t know which one. What is the conditional probability that the affected person is a woman? Suppose we know two of the three people have Alzheimer’s disease. What is the conditional probability that they are both women?
