Suppose that a blood test will produce 97% true positive results for people with a disease and and 95% true negative results for those lucky enough to not have the disease. Suppose, we also know that 0.5% of the general population has this disease at any one time. What is the probability that a randomly selected individual with a positive test actually has the disease?

Resubmitting this question. This was given as a sample question for a review.  I'm not taking a test now, and I'd appreciate a solution because something similar might show up in a future test... Isnt answering to help understand concepts the whole point of this site?  This isnt even in a graded assignment. This was just a sample problem.  I'd appreciate a response please.
