Exercise 9.34 Choose a postmenopausal woman at random. The probability is 0.40 that the woman chosen has osteopenia (low bone density) and 0.07 that she has osteoporosis (pathologically low bone mineral density). (Recall: P(A OR B) = P(A) + P(B) if A and B are disjoint)

a)Sample Space = { Osteopenia, Osteoporosis, Healthy}.

b) What must be the probability that a randomly chosen postmenopausal woman has a healthy bonedensity? P(Healthy) =

c) What is the probability that a randomly chosen postmenopausal woman has some problem with low bone density (osteopenia OR osteoporosis)? P(osteopenia OR osteoporosis) =
