The scuba instructor said that the occasional nurse shark might swim near the reef, but it is not an aggressive species. Seeing a shark was improbable, but he said not to panic if we do. What does the term improbable mean in this context?

Answer 1

In this context, the term "improbable" means that it is unlikely or not very common for a nurse shark to swim near the reef during your diving experience. While it is possible it could happen, the instructor is indicating that the chances of encountering a shark in that specific situation are low.
