Question 1061835
Consider a sample population of 100,000. Then .004 x 100,000, or 400 actually have the disease. Out of these 400, 96%, or 384 will test positive. Out of the 99,600 who don't have the disease, 4%, or 3,984 will test positive. Therefore, the probability that someone who tested positive will actually have the disease is 384/384+3984, or 0.0879121
