Use the sets below to answer parts (a) through (f). U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20} A: the numbers in U that divide 10 with no remainder B: the numbers in U that divide 15 with no remainder C: the numbers in U that divide 18 with no remainder. Make a clear Venn diagram showing the sets U, A, B, and C.
