Question

what is set,subset,venndigram,etc

Answer 1

Hi,

Here is your answer,

First part of your question ( Q.1 What is a set ? )

Answer. Set is a collection of well defined objects which are distinct from each other. Sets are usually denoted by capital letters A,B,C,......... and elements are usually denoted by small letters a , b , c ..........

If α is an element of a set A, then we write α ∈ A and say α belongs to A or α is in A or α is a member of A. If α does not belong to A, we write it as α ∉ A.

I hope you have understood what is a set.

Second part of your question. ( Q.2 What is a subset ? )

Answer. Well, Subset is also knows as Superset. So let us consider A and B be two sets. If every element of A is an element of B, then A is called subset of B and B is called superset of A.

A ⊆ B (OR) B ⊇ A

I hope you have understood what is a Subset.

Third part of your question ( What is a Venn Diagram ? )

Answer. So in a Venn diagram the universal set is represented by a rectangular region and a set is represented by circle or a closed geometrical figure insider the universal set.

I hope you have understood what is a Venn's Diagram.

If you have any doubt regarding this chapter ''SETS'' then do let me know.

Hope it helps you !
