$\{3\}$ is a subset of $(0, 3)$, true or false?
I'm inclined to say true, however my textbook is indicating that it's false because $\{3\}$ is a set and $(0,3)$ is an interval. Perhaps I'm reading that out of context. Am I on the right path?

No $3\not\in (0,3)$. Threfore, $\{3\}$ cannot be a subset of $(0,3)$.
