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: 5.3% of those under the age of 18, 12.6% of those ages 18–64, and 1.4% of those 65 and older do not have health insurance. Suppose 22.3% of people in the county are under age 18, and 62.1% 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.)
