What is (A ∪ B) – C, if A = {1, 2, 3, 4, 5, 6}, B = {2, 4, 5, 6} and C = {1, 2, 4, 6} ?
Answer: D. {3, 5}
Difference of two sets
—-The DIFFERENCE OF SETS is defined by identifying the set of elements of set a that are not an element of set b.
—- means 'elements of set a that are not in set b.'
(A ∪ B) – C
—- It means 'the union of set a and b that are not in set c.'
A = {1, 2, 3, 4, 5, 6}
B = {2, 4, 5, 6}
C = {1, 2, 4, 6}
A ∪ B = {1, 2, 3, 4, 5, 6}
(A ∪ B) – C = {3, 5}
