Final answer:
The events of forgetting to set your alarm and being late to class are dependent events.
Step-by-step explanation:
In order to determine if two events are independent, we need to check if the probability of the intersection of the events is equal to the product of the individual probabilities of the events.
In this case, the events A (Forgetting to set your alarm) and B (Being late to class) are not independent. For example, if you forget to set your alarm, the chance of being late to class is significantly higher. Therefore, the knowledge that one event occurred affects the chance of the other event occurring. Hence, A and B are dependent events.
