Let U = {9, 10, 11, 12, 13, 14, 15, 16, 17, 18}, A = {10, 12, 14, 16}, B = {13, 17}, and C = {10, 13, 16, 17, 18}. List all the members of each of the sets. (Enter solutions from smallest to largest. If there are any unused answer boxes, enter NONE in the last boxes.)

A ¿ B ¾ C with a - over A ¿ B.

I came up with {10, 15, NONE.} Is this correct?
