Answer:
A ∪ B = {2, 4, 6, 8 10}
Step-by-step explanation:
Given the following set notation:
U = {x|x is a counting number less than 11)
A = {x|x is a number divisible by 4 but less than 12} ← This means it doesn't include 12!
B = {x|x is a multiple of 2 between 2 and 10}
U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
The following are the elements of A and B:
A = {4, 8}
B = {2, 4, 6, 8, 10}
Therefore, the union of A and B are:
A ∪ B = {2, 4, 6, 8 10}
