Given:

U = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,}

Question:

A = {0, 2, 4, 6, 8} and B = {1, 3, 5, 7, 9}. What is AUB?

A. AUB = U

B. AUB = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

C. AUB = 0

D. AUB = {1, 2, 3, 4, 5, 6, 7, 8, 9}

( None of the choices )

Explanation:

  • U or union is to get all the given of the given sets of A, B, C and more. In this case we find the correct answer.

A = {0, 2, 4, 6, 8}

B = {1, 3, 5, 7, 9}

AUB = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

Note: We find on the choices when it's ∩ or intersection not using union. So the set of A∩B in your choices is letter C.

SETS

Given U = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} A = {0, 2, 4, 6, 8} and B = 1, 3, 5, 7, 9}. What is AUB?

A. AUB=U

B. AUB = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

C. AUB=0

D. AUB = {1, 2, 3, 4, 5, 6, 7, 8, 9}

UNION (AUB)

  • All elements of set A and set B are united.

A = {0, 2, 4, 6, 8}

B = {1, 3, 5, 7, 9}

AUB = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

Thus, the answer is None of the Choices.
