The set shown in the image is:

\[
\{a, 1, 3, b, 3, 81\}
\]

Now, in sets, repeated elements are not counted more than once. Here, the element `3` appears twice, but we only count it once. Thus, the distinct elements in the set are:

\[
\{a, 1, 3, b, 81\}
\]

Therefore, the set contains **5 distinct elements**.

**Tip:** Sets do not allow duplicate elements, unlike lists or multisets where repetitions are counted.

Learn how to count distinct elements in a set with repeated elements. In this problem, the set contains {a, 1, 3, b, 3, 81}, and we find that there are 5 distinct elements after removing duplicates. This explanation is perfect for students in Grades 6-8 studying basic set theory.
