Only 1% of the population are exposed to lead. I was randomly tested for lead. According to the manufacturer of the test, it tests positive whenever there is trace of lead in the blood, but also tests a false positive 5% of the times there is no trace of lead in the blood. Well, I tested positive (wouldn't be writing this long intro otherwise). What is the probability I was actually exposed to lead?
