According to the Prostate Cancer Foundation, prostate cancer will strike 1 in 6 American men. Therefore, the probability that an American man will develop prostate cancer is 0.167. Assume that a random sample of 30 men was taken. Let X be the number of American men who develop prostate cancer. It should be noted that X has a binomial distribution with n = 30 and p = 0.167. P(X = x) = 30C(x) * (0.167)^x * (0.833)^(30-x), where x = 0, 1, 2, ..., 30. a. Find the probability that exactly five men from the sample will develop prostate cancer. Answer:

An institute estimates that 2% of men in their 60s get prostate cancer. A test can typically identify correctly 95% of cancer cases and 95% of cases without cancer. If a man in her 60s gets a positive test result, what is the probability that he really has prostate cancer? 83.1% 27.9% 61.6% 37.0%
