Every day, two student council members are randomly chosen to read the morning announcements. Students cannot be chosen more than once to read the announcements. Jeremy designed a simulation for the selection of the students and gathered data to predict the probability that a seventh grade student will be chosen. In Jeremy’s simulation, he rolls two number cubes in each of 40 trials. In each trial, a cube landing on 1 or 2 represents a student in grade 7 being selected, and a cube landing on 3, 4, 5, or 6 represents a student in grade 8. Which statement best describes the flaw in Jeremy’s model?
The number of sides on a cube does not match the number of grade levels.
The number of sides on a cube is not a factor of the total number of students.
The number of outcomes representing each grade level does not change after the first student is chosen.
The number of outcomes representing a student in grade 7 is not the same as the number representing a student in grade 8.
