Answer:
1. { a, b, c, d, e, h }
2. { f, g, i }
Step-by-step explanation:
Given sets,
A = {a, b, c, d, e},
B = {a, c, f, g, i}
Universal set , ∪ = {a, b, c, d, e, f, g, h, i},
1. Since, = elements of universal set which are not in set B
= U - B
= { b, d, e, h },
Thus,
= All elements of A and
= { a, b, c, d, e, h }
2. B - A = elements of set B which are not in set A
= { f, g, i }
