Find the complement of the set given that
U = {3, 4, 5, 6, 7, 8, 9, 10, 11}.
(Enter your answers as a comma-separated list.)
{5, 7, 9, 10}

To find the complement of a set, we need to determine which elements of the universal set \( U \) are **not** in the given set. The universal set \( U \) is defined as:

\[
U = \{3, 4, 5, 6, 7, 8, 9, 10, 11\}
\]

The given set is:

\[
A = \{5, 7, 9, 10\}
\]

The **complement** of set \( A \), denoted by \( A' \), is the set of elements that are in \( U \) but not in \( A \). 

Now, let's find \( A' \):

1. Identify the elements in \( U \) that are **not** in \( A \).

\[
A' = \{3, 4, 6, 8, 11\}
\]

So, the complement of the set is:

\[
\{3, 4, 6, 8, 11\}
\]

### Final Answer:
The complement of the set is: **3, 4, 6, 8, 11**
