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.
Has Health Does Not Have
Age 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)
