What is the probability that one or both parents are hyperlipidemic?

Problem 2: (5 marks)
Hyperlipidemia in children has been hypothesized to be related to high cholesterol in their parents. The data in Table 5–11 were collected on parents and children.
a. What is the probability that one or both parents are hyperlipidemic?
b. What is the probability that a child and both parents are hyperlipidemic?
c. What is the probability that a child is hyperlipidemic if neither parent is hyperlipidemic?
d. What is the probability that a child is hyperlipidemic if both parents are hyperlipidemic?
