In answering a question on a multiple choice test, a student either knows the answer or guesses. Let `3/5\ ` be the probability that he knows the answer and `2/5` be the probability that he guesses. Assuming that a student who guesses at the answer will be correct with probability `1/3,` what is the probability that the student knows the answer, given that he answered it correctly?
