If A and B are two sets such that A ⊂ B, then what is A ∪ B?
Given that,
A and B are two sets
To find A ∪ B when A ⊂ B
If A and B are two sets such that A ∪ B, then A ∪ B = B
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).
