Suppose that a fair, 6 sided die is rolled. Let X indicate the event that an even number is rolled (in other words, X = 1 if an even number is rolled and X = 0 otherwise). Let Y indicate the event that 1, 2, or 3 is rolled (in other words, Y = 1 if 1, 2, or 3 is rolled and Y = 0 otherwise). Find P (X = 0, Y = 1).
