Answer 1

Answer:

Infinite set :

• A set containing uncountable elements called as infinite set

• Example : {1, 2, 3, 4, ...... }

Singleton Set :

• A set containing only single or one element is called Singleton set

• Example: {1}

Null Set :

• A set containing no elements is called as null set

• Example : { }

Disjoint set :

• Two sets containing different different elements is called as disjoint sets.

Extra information:-

⇒ A set is a collection of well defined objects .

⇒ Well defined collection of objects means - All the objects in the set should have a common property.

⇒ We should denote a set by upper case letters like A, B, C.... etc

⇒ Each object in a set is called as element

⇒ Every set is a collection but every collection is not be a set
