Call a household prosperous if its income exceeds $100,000. Call the household educated if the householder completed college. Select an American household at random, and let A be the event that the selected household is prosperous and B the event that it is educated. According to a survey, P(A) = 0.139, P(B) = 0.272, and the probability that a household is both prosperous and educated is P(A and B) = 0.085. What is the conditional probability that a household is prosperous, given that it is educated? (Round your answer to four decimal places.)
