Lung cancer is the leading cause of cancer-related deaths in the United States. Researchers examined the idea of testing all Medicare-enrolled heavy smokers for lung cancer with a computed tomography (CT) scan every year. In this population, the lifetime chance of developing lung cancer is high. In any given year, approximately 3% of heavy smokers develop lung cancer. The CT scan positively identifies lung cancer 89% of the time, and it gives a negative result for 93% of individuals who do not have lung cancer.

a. Use probability notation to express the three values cited.
b. Make a probability tree representing the outcomes in the sample space of Medicare-enrolled heavy smokers. Be sure to place probability values on all the branches of your tree.
c. What percent of CT scans in this target population would be positive?
d. What is the probability that a Medicare-enrolled heavy smoker who gets a positive CT scan actually has lung cancer, (cancer ? positive)?
