Question 15 (1 point)

Given the following definitions:
U = {1, 2, 3, 4, 5, 6, 7}
A = {1, 2, 4, 5]
B = {1, 3, 5, 7}
How many elements are in AUB?

Answer 1

Explanation:

The union is defined as the set of all elements in at least one of the sets.

`A \cup B=\{1,2,3,4,5,7\}`

So, there are 6 elements.
