Find A ∩ B, if A = {4, 7, 10, 13, 17} and B = {3, 5, 7, 9}.

Solution:

In mathematics, a set is a well-defined collection of objects.

Sets are named and represented using a capital letter.

In the set theory, the elements that a set comprises can be any kind of thing: people, letters of the alphabet, numbers, shapes, variables, etc

Given:

Sets are A = {4, 7, 10, 13, 17} and B = {3, 5, 7, 9}

A ∩ B is the intersection of set a and b.

Elements present in A = {4, 7, 10, 13, 17}

Elements present in B = {3, 5, 7, 9}

Elements present in both A and B = A ∩ B

A ∩ B = {7}

Therefore,

A ∩ B = {7}.

Find A ∩ B, if A = {4, 7, 10, 13, 17} and B = {3, 5, 7, 9}.

Summary:

If A = {4, 7, 10, 13, 17} and B = {3, 5, 7, 9}, then A ∩ B = {7}.
