the probability that an individual without a college education earns more than $100,000 is 0.4, whereas the probability that a person with a b.s. or higher degree earns more than $100,000 is 0.6. the probability that a person chosen at random has a b.s. degree is 0.4. what is the probability that a person has at least a b.s. degree if it is known that he or she earns more than $100,000?
