One prominent physician claims that 70% of patients with lung cancer are chain smokers. a) Suppose that 10 patients with lung cancer are admitted to a hospital. Calculate the probability that fewer than half of the patients are chain smokers. b) suppose that 20 patients with lung cancer are admitted to the hospital. Calculate the probability that fewer than half of the patients are chain smokers.
