Final answer:
To determine the probability of Enrique participating in after-school activities based on living 7 miles from school, we would need specific data relating participation to distance from school, which is not provided.
Step-by-step explanation:
The question "What is the probability that Enrique participates in after-school activities given that he lives 7 miles from school?" requires additional context to be answered accurately. Specifically, we would need the probability of students participating in after-school activities conditioned on how far they live from the school or relevant data about students' participation in after-school activities in relation to their distance from school. Without this information, we cannot calculate the requested probability.
However, based on similar examples provided, we can infer that the subject matter here concerns calculating conditional probabilities and understanding the relationship between different probabilistic events. For example, if we knew that a certain percentage of students living 7 miles away do participate in after-school activities, we could use this to calculate the desired probability for Enrique.
