Question

A={X/X is a prime number less than 10}B={ X/X €N x is a factor of 8} find A U B,A ∩ B​

Answer 1

Answer:

AUB={1,2,3,4,5,7,8}

A∩B={2}

Step-by-step explanation:

A={2,3,5,7}

B={1,2,4,8}

✒AUB={2,3,5,7}U{1,2,4,8}

AUB={1,2,3,4,5,7,8}

✒A∩B={2,3,5,7}∩{1,2,4,8}

A∩B={2}

Answer 2

Answer:

A U B = {1, 2,3, 4, 5,7,8}

A ∩ B = {2}

Step-by-step explanation:

Given,

A= {X/X is a prime number less than 10}

B= { X/X €N x is a factor of 8}

Then,

A= {2,3,5,7}

B = { 1,2,4,8}

A U B = Set in which all the elements of A and B are present

A U B = {1, 2,3, 4, 5,7,8}

A ∩ B​ = Set in which the elements common to A and B are present

A ∩ B = {2}
