Given;
U = {1,2,3,4,5,6,7,8,9},
A = {1,2,3,4,5,6},
B = {2,4,5,6},
C = {1,6,7}.
To find;
A∩B, A∪C, (AUB)∩(A∪C), A'∩B', (A∩C)', A∪C, A∩(B∪C), A', A'∪B', A-B, A∪B, A∪(B∪C), B', (AUB)', B-C
A∩B = {2,4,5,6,}
A∪C = {1,2,3,4,5,6,7}
(AUB)∩(A∪C) = {1,2,3,4,5,6}
A'∩B' ={7,8,9}
(A∩C)' = {2,3,4,5,7,8,9}
A∪C = {1,2,3,4,5,6,7}
A∩(B∪C) = {1,2,4,5,6}
A' = {7,8,9}
A'∪B' = {1,3,7,8,9}
A-B = {2,4,5,6}
A∪B = {1,2,3,4,5,6}
A∪(B∪C) = {1,2,3,4,5,6,7}
B' = {1,3,7,8,9}
(AUB)' = {7,8,9}
B-C = {6}
