Which set of numbers could be the universal set for the set given below?
- P = set of integers which are multiples of 4.
- T = set of all even square numbers.
Given the universal set = {x : x ∈ N and x < 20}, find:
C = {x : x is divisible by 4}
Given, universal set = {x : x ∈ N, 10 ≤ x ≤ 35}.
A = {x ∈ N : x ≤ 16} Find: A'
