For any two sets A and B, prove that B ⊂ A ∪ B
B ⊂ A ∪ B
Let us consider an element ‘p’ such that it belongs to B
p ∈ B
p ∈ B ∪ A
If A = {x : x ϵ R, x < 5} and B = {x : x ϵ R, x > 4}, find A ∩ B.
Prove that A – B = A ∩ B.’
Find the symmetric difference A Δ B, when A = {1, 2, 3} and B = {3, 4, 5}.
Prove that A ∩ (A ⋃ B)’ = ϕ
If A = {3, {2}}, find P(A).
