Suppose a 4-sided die (with sides labeled 1, 2, 3, 4) is rolled 2 times.
(b) Let A denote the event that a 1 is obtained on the first roll, and let B denote the event that an even is obtained on the second roll. Find P(A and B).
(c) Find the probability that the second roll is exactly twice the first roll.
(d) Find the probability that the second roll is greater than or equal to the first roll.
