Probability Basicshard
0:00.0
A rare disease affects of a population. A diagnostic test has a variable sensitivity depending on the patient's age. The population is partitioned into two age groups: Group 1 (comprising of the population) and Group 2 (comprising of the population). The test's sensitivity (true positive rate) is for Group 1 and for Group 2. The false positive rate is for both groups. If a randomly selected person tests positive, what is the probability that they actually have the disease?
