Question

with reference to a universal set the inclusion of a subset in another is relation which is

Answer 1

With reference to a universal set, the inclusion of a subset in another is relation, which is reflexive, transitive and not symmetric

Step-by-step explanation:

A subset is a set whose elements are all members of another set. It is represented by the symbol "⊆".

With reference to a universal set, the inclusion of a subset in another is relation, which is reflexive, transitive and not symmetric.

Since A ⊆ A,

Relation ⊆ is reflexive.

Since A ⊆ B, B ⊆ C, then it implies that A ⊆ C

So relation ⊆ is transitive.

But if A ⊆ B Does not implies B ⊆ A

Relation is not symmetric.
