If a universal set U={3,4,5,6,7,8,9,10,11,12}A={4,6,8,10,12}B={3,5,7,9

1.	If a universal set U={3,4,5,6,7,8,9,10,11,12}A={4,6,8,10,12}B={3,5,7,9,11} then (A∪B)′ is
Answer» If a universal set $U = {3, 4, 5, 6, 7, 8, 9, 10, 11, 12} A = {4, 6, 8, 10, 12} B = {3, 5, 7, 9, 11}$ then $(A \cup B)^{'}$ is
