As a senior manager for a major health insurance company, you are interested in the relationship between education level and smoking for adults in the United States. According to recent data, 0.09 of adults in the U.S. lack a high school diploma, 0.30 have a high school diploma only, 0.28 have some college or an Associate's degree only, and the rest have at least a Bachelor's degree. Further, 0.40 of adults without a high school diploma smoke, 0.34 of adults with a high school diploma only smoke, 0.25 of adults with some college or an Associate's degree only smoke, and 0.14 of adults with at least a Bachelor's degree smoke. You select an adult in the U.S. at random. If the person smokes, use the conditional probability approach to determine the probability they have a high school diploma only.
