An urn contains 4 marbles. Each marble is either black or white. The number of black marbles could be either 0, 1, 2, 3, or 4; all these possibilities are equally likely. If you randomly sample 3 marbles with replacement and the sequence is white-white-black, what is the probability there are exactly 2 black marbles in the urn?
