Answer
# Brief Explanations:
1. Asking the first 50 people that arrive at his school: This is not representative as early - arriving students may have different music preferences (e.g., they could be more likely to be involved in early - morning activities and have different tastes than the general student population). So, it's No.
2. Asking every tenth person at a school concert he attends: People at a school concert are more likely to have an interest in music in general and a specific type of music that the concert features. This sample is biased towards music - loving students and not representative of all students. So, it's No.
3. Asking every third student who enters his school: This is a form of systematic sampling. If the selection is made without any other influencing factors related to music preference (such as time of entry being related to music - related activities), it has a better chance of representing the entire student population. So, it's Yes.
