probability set problems

11. If two six-sided dice are rolled simultaneously, what is the probability of getting doubles or the sum of the numbers on the two dice is equal to 6? 12. Given the following sets: Find: (a) AmB (b) (AUC)n(BUC) (6 points) U= {1,2, 3, ..., 12} A= {3, 6, 9,12} B = {2, 4, 6, 8,10,12} C = {4, 8,1 } (2 points) (4 points)
