Let a = {a, b, c, d, e} and b = {a, c, f, g, i}. universal set: ∪= {a, b,c, d,e, f,g, h,i}
1. a ∪ b^c
2. b - a

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 }
