The individual actually o had the disease Yes 336 No Positive Negative 4 15 1153 Find the probability of selecting a subject with a positive test result, given that the subject has the disease. (Round to three decimal places as needed.) Which of the following best describes what this probability represents in words? O A. Approximately 96% of individuals that actually have the disease will receive a positive test result. O B. Approximately 96% of individuals that receive a positive test result will have the disease. OC. Approximately 96% of all individuals will both have the disease and receive a positive test result. What would be a favorable consequence of this result? O A. The subject would receive treatment and would be unlikely to spread the disease. O B. The subject would experience needless stress and additional testing. O C. The test would be shown to be not reliable.
