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


Answer
a) {3} ("the common elements")
b) {3} ("the common elements")
c) {1,2,3,5,7} ("combining both groups")
d) {3,4,5,6,7} ("combining both groups")
e) {1,2,3,4,5,6}∩{3,5,7}={3,5}
f) {1,2,3}U{3,4,5,6,7}={3}
g) {3}∩{3,5,7}={3}
h) {3}U{3,5,7}={3,5,7}
