"One in thousand people have a prevalence for a particular heart disease. There is a test to detect this disease. The test is 100% accurate for people who have the disease, and is 95% accurate for those who do not (this means that 5% of people who do not have the disease will be wrongly diagnosed as having it). If a randomly selected person tests positive what is the probability that the person actually has the disease?"
