Question 1👑 VIP
A rare disease affects 2% of a population. A diagnostic test for the disease has a sensitivity of 95% (correctly identifies 95% of those who have the disease) and a specificity of 90% (correctly identifies 90% of those who do not have the disease). If a randomly selected person tests positive, what is the probability — rounded to the nearest percent — that they actually have the disease?
