Can someone show me the correct solution?

The Hudson Engineering Group (HEG) has contacted you to create conceptual model whose application will meet the expected database requirements for its training program. The HEG administrator gives you the following description of the training group's operating environment: The HEG has 12 instructors and can handle up to 30 trainees per class. HEG offers five "advanced technology" courses, each which may generate several classes If a class has fewer than 10 trainees in it, it will be canceled. It is, therefore possible for a course not to generate any classes. Each class is taught by one instructor. Each instructor may teach up to two classes or may be assigned to do research only. Each trainee may take up to two classes per year. Given this information, do the following: a Define all the entities and relationships. b. Describe the relationship between instructor and class in terms of connectivity and cardinality c. Draw Entity Relationship (ER) Diagram using the Chen model
