student is allowed to pass a test on three tries. The probability that the student passes the test on the first attempt is 0.5, that he passes on the second attempt (of course, given that he failed on the first attempt) is 0.7, and the probability that he passes on the third attempt is 0.8 (given he failed on the first two attempts). What is the probability that he will pass the test?
