You can put this solution on YOUR website! Given A = {1, 2, 3, 4}, B = {4, 5, 6,}, and C = {2, 6, 7}.
Evaluate each set
a) A ∩ B..........is { 4}
b) A U C..........is {1, 2, 3, 4, 5, 6}
c) B U C..........is {2,4, 5, 6, 7}
d) (A U B) ∩ C......... {1, 2, 3, 4}∩{2, 6, 7}...is { 2}
e) A U (B U C).........{1, 2, 3, 4}U{2,4, 5, 6, 7}...is {1,2,3,4, 5, 6, 7}
f) (A ∩ B) ∩ C.....{ 4}∩{2, 6, 7}.....is { }
g) (A ∩ B) U C ....{ 4}U{2, 6, 7}...is {2,4, 6, 7}
