I need help with the following HW problem

9. Suppose that we have an urn with 10 balls, 6 of which are white and 4 of which are black. Let X be the random vari- able representing the number of white balls chosen when n balls are randomly chosen from the urn (with replacement). Suppose that sample of 3 balls is randomly chosen (with replacement). (a) What is the probability that two of the chosen balls are white? (b) What is the expectation value for X
