Explanation Calculation: There are total 1323 patients considered in this study. We have to find the probability that a patient had stomach upset given that the patient was in the ibuprofen group. This probability can be calculated as: The required probability = number of patients in ibuprofen group had stomach upset number of patients in ibuprofen group From contingency table , there are 8 patients in ibuprofen group had stomach upset and there are total 672 patients in ibuprofen group. We put these values in the above formula as: The required probability = 8 672 = 0.01190 ≈ 0.012 We have to find the probability that a patient had stomach upset given that the patient was in the placebo group
