Answer 2

Hope it helps

Step-by-step explanation:

An improper subset includes  ϕ  and the set itself …

For example ,consider a set A={1,2,3}

It’s subsets will be  ϕ  , {1} , {2} , {3} , {1,2} , {2,3} , {1,3} , {1,2,3} .

Here, {1} , {2} , {3} , {1,2} , {2,3} , {1,3} are called proper subsets of the set A whereas the subsets  ϕ  and {1,2,3} are considered as improper subset ..

Proper subset is denoted as  ⊂  , i.e. , {1}  ⊂  A , {2}  ⊂  A , and so on …

An improper subset is denoted as  ⊆  , i.e. ,  ϕ   ⊆  A and {1,2,3}  ⊆  A …
