Let D= {2,5,7}, E={2,4,5,6} and F={1,3,4,5,7} List the elements in the set D U E.

Answer 1

The set D U E (D union E) is the set that contains all the elements in set D and set E, without any duplicates.

D = {2, 5, 7}
E = {2, 4, 5, 6}

To find the D U E, we combine the elements from both sets without any duplicates.

D U E = {2, 4, 5, 6, 7}
