Question

Let A = {1, 2, 3, 4, 5} and B = {2, 4, 6, 8, 10}. What is A∪B (union)?

a) {1, 2, 3, 4, 5, 6, 8, 10}
b) {2, 4}
c) {1, 3, 5}
d) {1, 2, 3, 4, 5, 6, 8, 10}

Answer 1

The union of sets A = {1, 2, 3, 4, 5} and B = {2, 4, 6, 8, 10} is {1, 2, 3, 4, 5, 6, 8, 10}, which is a combination of all the unique elements from both sets.

Step-by-step explanation:

To find the union of sets A and B, which is written as A∪B, we combine all the unique elements from both sets without duplicating any elements. Given A = {1, 2, 3, 4, 5} and B = {2, 4, 6, 8, 10}, the union of these two sets includes every element that appears in either set A, or set B, or in both. Therefore, the union of sets A and B is equal to {1, 2, 3, 4, 5, 6, 8, 10}.
