The value of the set operation A U ∅ is {3, 4, 5, 6}
<h3>How to evaluate the set operation?</h3>
The elements of the sets are given as:
U = {1, 2, 3, 4, 5, 6}
A = {3, 4, 5, 6}
To calculate the set A U ∅, we use the following illustration
A U ∅ = set A combined with an empty set
This gives
A U ∅ = {3, 4, 5, 6} combined with an empty set
This gives
A U ∅ = {3, 4, 5, 6}
Hence, the value of the set operation A U ∅ is {3, 4, 5, 6}

Answer:
72 percent of the total houses are small
Step-by-step explanation:
The first step is to know the total apartments from the ratio: This is got by adding 18 + 7 = 25
The ratio of small apartments to regular ones is 18:7
To get the percentage that is small, we have to express the number of small houses when compared to the total available apartments. (<em>Note: not the regular ones) </em>as a percentage.
This will be (18/25) X 100 = 72%
Therefore, 72 percent of the total houses are small
