Question

let A = {x:x is a prime number less than 50} and B = {x:x is an odd number less than 50} find A-B with the help of venn diagram​

Answer 1

Step-by-step explanation:

Given:-

A = {x:x is a prime number less than 50} and

B = {x:x is an odd number less than 50}

To find:-

Find A-B with the help of venn diagram

Solution:-

Given sets are

A = {x:x is a prime number less than 50}

A={2,3,5,7,11,13,17,19,23,29,31,37,41,43,47}

B = {x:x is an odd number less than 50}

B={1,3,5,7,9,11,13,...,45,47,49}

A-B=

{2,3,5,7,11,13,17,19,23,29,31,37,41,43,47}-{1,3,5,7,9,11,13,...,45,47,49}

A-B ={2}

It is a singleton set.

Answer:-

A-B for the given problem is {2}

Used Concept:-

• The difference of two sets A and B is denoted by A-B and it is defined by The elements are in only the set A.
• A-B={ x∈A and x∉B}
