Question

properties of union of sets​

Answer 1

Step-by-step explanation:

A ∪ B = B ∪ A (Commutative law)

(A ∪ B) ∪ C = A ∪ (B ∪ C) (Associative law )

A ∪ ∅ = A (Law of identity element, ∅ is the identity of ∪)

A ∪ A = A (Idempotent law)

U ∪ A = U (Law of U)

Answer 2

Answer:

Commutative Properties: The Commutative Property for Union and the Commutative Property for Intersection say that the order of the sets in which we do the operation does not change the result. General Properties: A ∪ B = B ∪ A and A ∩ B = B ∩ A.
