Question

Set A = {2, 4, 5}

Set B = {2, 6, 11}

What is A U B?

Answer 1

A ∪ B = {2, 4, 5, 6, 11}

Explanation:

The union of 2 sets means the combined set will have the elements of both Set A and Set B. Also note that any common element is not repeated, it is only written once.

• Set A = {2, 4, 5}
• Set B = {2, 6, 11}

⇒ A ∪ B = {2, 4, 5, 6, 11}

Answer 2

A U B = {2, 4, 5, 6, 11}

Explanation:

The union of two sets is a set that contains every element that is in either set.

Set A = {2, 4, 5}

Set B = {2, 6, 11}

A U B = {2, 4, 5, 6, 11}
