Unfortunately, as an AI text-based model, I cannot draw images or diagrams. However, I can explain the cardinalities between the "Student" and "Course" entities based on the given information.

The cardinality refers to the relationship or association between two entities in a database. In this case, we have the "Student" entity and the "Course" entity.

Based on the information given, we can assume the following cardinalities:

- Each student can be enrolled in multiple courses. This indicates a "one-to-many" relationship between the "Student" entity and the "Course" entity. Specifically, one student can have many courses.

- Each individual course can have multiple students enrolled in it. This also indicates a "one-to-many" relationship between the "Course" entity and the "Student" entity. Specifically, one course can have many students.

To represent this in an Entity-Relationship Diagram (ERD), you would use appropriate symbols and lines to connect the "Student" entity and the "Course" entity, indicating the cardinalities described above.
