Suppose a fair six-sided die is rolled five times. a) Assume the faces are labeled with 1, 2, 3, 4, 5, 6. What is the probability that we obtain five distinct values? b) If the face with 6 is relabeled with another 5, so we have 1, 2, 3, 4, 5, 5. What is the probability that we obtain five distinct values?
