Question

Which sample fairly represents the population? Check all that apply. measuring the heights of every fiftieth person on the school roster to determine the average heights of the boys in the school calling every third person on the soccer team’s roster to determine how many of the team members have completed their fundraising assignment observing every person walking down Main Street at 5 p.m. one evening to determine the percentage of people who wear glasses sending a confidential e-mail survey to every one-hundredth parent in the school district to determine the overall satisfaction of the residents of the town taking a poll in the lunch room (where all students currently have to eat lunch) to determine the number of students who want to be able to leave campus during lunch

Answer 1

Your question is really hard to read, but I'll give my best to give you an appropriate answer. 

Generally, a sample which best represents the population would usually be one which makes it equally likely for everyone to be included into that sample. 

observing every person walking down Main Street at 5 p.m. one evening to determine the percentage of people who wear glasses

and measuring the heights of every fiftieth person on the school roster to determine the average heights of the boys in the school calling every third person on the soccer 

Are surely two. It is questionable if any of the other ones are really randomized and represent the population fairy well or not.
