A health statistics agency in a certain country tracks the number of adults who have health insurance. Suppose according to the agency, the uninsured rates in a recent year are as follows: 5.2% of those under the age of 18, 12.8% of those ages 18–64, and 1.4% of those 65 and older do not have health insurance. Suppose 22.4% of people in the county are under age 18, and 61.9% are ages 18–64. (a) What is the probability that a randomly selected person in this country is 65 or older? (b) Given that a person in this country is uninsured, what is the probability that the person is 65 or older? (Round your answer to three decimal places.)
