Refer to the minitab display to the right. the probabilities were obtained by entering the values of n equals 5n=5 and p equals 0.165p=0.165. in a clinical test of a drug, 16.516.5% of the subjects treated with 10 mg of the drug experienced headaches. in each case, assume that 55 subjects are randomly selected and treated with 10 mg of the drug. find the probability that at least four of the subjects experience headaches. binomial with n equals 5n=5 and p equals 0.165p=0.165 x p(xequals=x) 0 0.40590.4059 1 0.40110.4011 2 0.15850.1585 3 0.03130.0313 4 0.00310.0031 5 0.00010.0001 the probability that at least four of the subjects experience headaches is nothing.
