Hi,
U ={1,2,3,4,5,6,7,8,9,10,12,14}
A ={2,4,6,8,10,12}
A' ={1,3,5,7,9,14}
B ={1,3,2,5,8,10,14}
B' ={4,6,7,9,12}
A ={2,4,6,8,10,12}
B ={1,3,2,5,8,10,14}
A ᑎ B = {2,8,10}
(A ᑎ B)' = {1,3,4,5,6,7,9,12,14}
A' ={1,3,5,7,9,14}
B' ={4,6,7,9,12}
A' U B' = {1,3,4,5,6,7,9,12,14}
DeMorgan's law, A' U B' = (A ᑎ B)'
