The issue of health care coverage in the United States is becoming a critical issue in American politics.

A large-scale study was undertaken to determine who is and is not covered. From this study, the following table of joint probabilities was produced.

Age Has Health Does Not Have Category Insurance Health Insurance 25–34 .167 .085 35–44 .209 .061 45–54 .225 .049 55–64 .177 .026

If one person is selected at random, find the following probabilities.

a. P(Person has health insurance)

b. P(Person 55–64 has no health insurance)

c. P(Person without health insurance is between 25 and 34 years old)
