During a clinical trial the effect of two treatments and a control for treatment of hepatitis C were considered. The following table provides the total patients in each group and the number that showed a complete (positive) response after 24 weeks of treatment. Complete Response Total Ribavirin plus interferon alfa 13 22 Interferon alfa 9 18 Untreated controls 0 20 Suppose that a patient is selected at random from this set. Let A denote the event that the patient is treated with ribavirin plus interferon alfa, and let B denote the event that the response is complete. Determine the following probabilities. Round your answers to three decimal places (e.g. 98.765). (a) P(BIA) = (b) P(AB) = (c) P(A|B') = (d) P(A' B) = i i
