Anew medical test has been designed to detect the presence of the mysterious brainlesserian disease. among those who have the disease, the probability that the disease will be detected by the new test is 0.7. however, the probability that the test will erroneously indicate the presence of the disease in those who do not actually have it is 0.04. it is estimated that 19 % of the population who take this test have the disease.
if the test administered to an individual is positive, what is the probability that the person actually has the disease?
30. factories a, b and c produce computers. factory a produces 2 times as many computers as factory c, and factory b produces 7 times as many computers as factory c. the probability that a computer produced by factory a is defective is 0.032, the probability that a computer produced by factory b is defective is 0.034, and the probability that a computer produced by factory c is defective is 0.056.
a computer is selected at random and it is found to be defective. what is the probability it came from factory c?
