Final answer:
Emmy experiences high interpersonal justice due to her professor's polite behavior, but low procedural justice because she didn't receive a clear explanation for her grade.
Step-by-step explanation:
Emmy likely experiences high interpersonal justice and low procedural justice. Interpersonal justice refers to the fairness and respect with which one is treated by others, and in Emmy's case, her professor was polite and kind. Procedural justice, on the other hand, pertains to the transparency and consistency of processes leading to outcomes; in this context, it indicates how the grading was conducted and communicated. Since the professor did not explain how Emmy earned her grade, she received poor procedural justice, despite the high interpersonal justice due to the professor's behavior.
