Question
Given, universal set = {x : x ∈ N, 10 ≤ x ≤ 35}.
A = {x ∈ N : x ≤ 16} Find: A'
Solution
Universal set = {x : x ∈ N, 10 ≤ x ≤ 35}
= {10, 11, 12, 13, 14, 15,....,34, 35}
A = {x ∈ N : x ≤ 16}
= {{10, 11, 12, 13, 14, 15, 16}
A' = {17, 18, 19, 20, 21, 22,.....,33, 34, 35}
= {x : x ∈ N ; 17 ≤ x ≤ 35}
