Question

If A={x:x is a prime and x<10},B={x:x is a factor of 6}. then find A intersection B,A union B and A-B​ ​

Answer 1

Answer:

A={ 2,3,5,7}

B= { 1,2,3,6}

AUB = {2,3,5,7} U {1,2,3,6}

= {1,2,3,5,6,7}

Therefore AUB= {1,2,3,5,6,7}

A intersection B = {2,3,5,7} intersection {1,2,3,6}

={2,3}

Therefore A intersection B ={2,3}

A-B = {2,3,5,7} - {1,2,3,6}

Eliminating the common elements from A&B

Therefore A-B = {5,7}
