1. suppose that 5% of people of your age and heredity have diabetes.
Suppose that a blood test has been developed that correctly gives a positive
test result in 80% of people with diabetes, and gives a false positive in
20% of the cases of people without diabetes. Suppose you take the test, and
it is positive. What is the probability that you actually have diabetes,
given the positive result?
我怎么觉得和5%无关呢?
