We know that the probability of someone lying is about 0.1. With this information, researchers decide to look into a new lie detector test. From their study, they determined that the probability of the lie detector returning a positive result when a subject lied, is 0.99. The probability of the lie detector returning a negative result, when the subject DID NOT lie, is 0.975. What is the probability that a person lied, given that the lie detector yields a positive result?
