[8]. The estimates are given in Table 3.5. Suppose an unrelated 77-year-old man, 76-year-old woman, and 82-year-old woman are selected from a com- munity. 3.16 What is the probability that all three of these individu- als have Alzheimer's disease? 3.17 What is the probability that at least one of the women has Alzheimer's disease? 3.18 What is the probability that at least one of the three people has Alzheimer's disease? 3.19 What is the probability that exactly one of the three people has Alzheimer's disease? 3.20 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? 3.21 Suppose we know two of the three people have Alzheimer's disease. What is the conditional probability that they are both women? 3.22 Suppose we know two of the three people have Alzheimer's disease. What is the conditional probability that they are both younger than 80 years of age?
