Let U={1,2,3,4,5,6,7,8,9,10} be a universal set and define the following.

A={x∈U∣x<7} and B={x∈U∣x>3}

Find A∪B and A∩B. Present your answer by listing the elements of the sets.

A∪B=
A∩B=

- A={−9,−4,7,9,10-9,-4,7,9,10} y B={−9,−5,−2,0,7-9,-5,-2,0,7}

A∪B=

-Let U be the universal set, where:
U={1,2,3,...,18,19,20}
Let the sets A and B be subsets of U, where:

Set A = {5,7,13, 14,16}

Set B = {2,10,11,14,16,17}

Find the following:

LIST the elements in the set A∪B:
A∪B =
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE

LISTS the elements of the set A∩B:
A∩B =
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE
