Question

Pls answer my question :)​

Answer 1

U={1,2,3,4,5,6,7,8,9,10,11}

A={4,8,12}

B={2,4,6,8,10}

A union B ( A U B ) = { 2,4,6,8,10,12}

ans: { 2,4,6,8,10,12}

Answer 2

A ∪ B = {2, 4, 6, 8 10}

Explanation:

Given the following set notation:

U = {x|x is a counting number less than 11)

A = x ← This means it doesn't include 12!

B = x

U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

The following are the elements of A and B:

A = {4, 8}

B = {2, 4, 6, 8, 10}

Therefore, the union of A and B are:

A ∪ B = {2, 4, 6, 8 10}
