The problem asks to find the complement of set $A$, denoted $A'$, with respect to the universal set $U$.

We are given:

• $U = \{1, 2, 3, 4, 5, 6, 7, 8, 9, 10\}$
• $A = \{2, 3\}$

The complement of $A$, denoted as $A'$, includes all elements in $U$ that are not in $A$. To find $A'$, we subtract the elements of $A$ from $U$:

$A' = U - A = \{1, 2, 3, 4, 5, 6, 7, 8, 9, 10\} - \{2, 3\} = \{1, 4, 5, 6, 7, 8, 9, 10\}$

None of the answer choices directly match this set, so it appears this question has an error. However, based on the available options:

• The correct complement of $A$ is $\{1, 4, 5, 6, 7, 8, 9, 10\}$.

Feel free to let me know if you'd like further details or have any questions!

Here are 5 related questions for more practice:

1. What is the complement of $B = \{1, 4, 7\}$ in $U = \{1, 2, 3, 4, 5, 6, 7, 8, 9, 10\}$?
2. How do you find the union of two sets?
3. What is the intersection of $A$ and $B = \{4, 5, 6\}$?
4. Can a complement of a set ever be empty?
5. What is the cardinality of the universal set $U$?

Tip: The complement of a set contains all elements from the universal set that are not present in the original set!
