Assume that if you have the disease, your testwill always come back positive, but if you do nothave the disease, there is still a 0.001 chance that youwill test positive. In reality, only 1 of 10,000 peoplehave the disease. Your doctor calls and says that youhave tested positive. He is sorry but there is a 99.9%(120.001) chance that you have the disease. Is hecorrect? What is the actual probability that you havethe disease?
