Question

Let U = {9, 10, 11, 12, 13, 14, 15}, A = {9, 10, 11, 12}, B = {9, 10, 13, 14}, and C = {11, 13, 15}. List all the members of the given set. (Enter your answers as a comma-separated list.)
(A ¾ B) ¿ C

Answer 1

Not sure what your characters are, but

(A∩B)∪C = {9,10}∪{11,13,15} = {9,10,11,13,15}

(A∪B)∩C = {9,10,11,12,13,14}∩{11,13,15} = {11,13}
