Question

Given A = {1, 2, 3, 4}, B = {4, 5, 6,}, and C = {2, 6, 7}. Evaluate each set
a) A ∩ B
b) A U C
c) B U C
d) (A U B) ∩ C
e) A U (B U C)
f) (A ∩ B) ∩ C
g) (A ∩ B) U C

Answer 1

A = {1, 2, 3, 4}, B = {4, 5, 6,}, and C = {2, 6, 7}.

a) A ∩ B = {4}
b) A U C = {1,2,3,4,6,7}
c) B U C = {2,4,5,6,7}
d) (A U B) ∩ C = {2,6}
e) A U (B U C) = {1,2,3,4,5,6,7}
f) (A ∩ B) ∩ C = {} empty set
g) (A ∩ B) U C = {2,4,6,7}
