Given the universal set = {x : x ∈ N and x < 20}, find :
A = {x : x = 3p ; p ∈ N}

Given, universal set = {x : ∈ N, 10 ≤ x ≤ 35}.
B = {x : x > 29} Find: B'.

Given A = {x : x ∈ N and 3 < x ~ 6} and 8 = {x : x ∈ W and x < 4}. Find: A ∪ B

For the universal set {4, 5, 6, 7, 8, 9, 10, 11,12,13} ; find the subset of A = {even numbers}.
Also, find a complement of A.

For the universal set {4, 5, 6, 7, 8, 9, 10, 11,12,13} ; find the subset of D = {even numbers less than 10}.
Also, find a complement of D.

If A = {4, 5, 6, 7, 8} and B = {6, 8, 10, 12}, find: B - A

If A = {3, 5, 7, 9, 11} and B = {4, 7, 10}, find: A ∩ B and n(A ∩ B)

If A = {3, 5, 7, 9, 11} and B = {4, 7, 10}, find: (A – B) and n(A – B)

If P = {x : x is a factor of 12} and Q = {x: x is a factor of 16}, find : n(P)

If P = {x : x is a factor of 12} and Q = {x: x is a factor of 16}, find : n(Q).
