Question

Let D = {12,15,17}, E = {12,14,15,16} and F= {11,13,14,15,17}. Find D U E

Answer 1

The union of sets D and E, denoted as D ∪ E, represents the combination of all unique elements from both sets D and E.

D = {12, 15, 17}

E = {12, 14, 15, 16}

To find D ∪ E, we simply list all the unique elements that appear in either D or E, without repetitions:

D ∪ E = {12, 15, 17, 14, 16}

So, the union of sets D and E is {12, 15, 17, 14, 16}.
