3. A new diagnostic test is developed for a rare disease which aspects 0.1% of all adults. Among people who actually have the disease, a positive result occurs 99% of the time, and among those who do not have the disease, a positive result occurs 2% of the time. (a) What is the probability that a random person has the disease and tests positive? (b) What is the probability the test returns positive? (c) A randomly selected individual is tested and the result is positive. What is the probability that the individual has the disease?
