I think so
Step-by-step explanation:
So, for question one, 50 people across 20 random places, this would be pretty random. A random sample is sampling from people who have the exact same probablity of getting chosen. So if all the people are random, it should be a random sample. Now for question 2, this is a random sample. If you surveyed completely random people from completely random high schools, then the entire thing is completely random. Therefore, both scearios are random samples.
