A class of 12 girls and 14 boys is going to choose 3 students to represent them in student government. Allie suggested that the first 3 students to arrive in class the next day should be the representatives. Bobby suggested that each student roll 2 numbers cubes and the 3 students with the highest sum should be the representatives. Whose method would result in a fair sample that represents the class population, and why?

rebeccaxhawaii (rebeccaxhawaii):

Bobby, because every student has an equal chance to get a high sum Bobby, because students with the highest sum will be the most popular students Allie, because students who arrive first in class are the most responsible Allie, because every student has an equal chance to arrive first in class the next day
