had annual check-ups and a biopsy at the end of the study. Prostate cancer was found in 804 of 4368 men taking Finasteride and in 1145 of the 4692 men taking a placebo. 1.) Assume that the true risk of developing prostate cancer for a man taking Finasteride is equal to the one in this sample. If 10 men from the Finasteride group are randomly selected, what is the probability that at least one of them will develop prostate cancer? Answer choices: a. 0.184 b. 0.816 c. 0.869 d. 0.131
