1. Suppose that researchers developed a test to detect a particular disease in the general population. However, the test was not perfect. To determine the accuracy of the test, a study was performed with 2000 participants, 1000 of whom were known to have the disease and 1000 of whom were known to not have the disease.
Participants with the disease that tested positive:950
Participants without the disease that tested positive: 150
Participants with the disease that tested negative:50
Participants without the disease that tested negative:850
Total positive tests:1100
Total negative tests:900

b. If you were to randomly choose a participant, what is the probability that a randomly chosen participant
tested positive?
