Refer to the Minitab below The probabilities were obtained by entering the values of n = 6 and p = 0.167. In a clinical test of the drug Lipitor 16.7% of the subjects treated with 10 mg of atorvastatin experienced headaches (based on data from Parke-Davis). In each case, assume that 6 subjects are randomly selected and treated with 10mg of atorvastatin, then find the indicated probability.
