Of all the students in a particular class, 20% have blue eyes. We want to run a simulation to predict how many blue eye students will be chosen if we randomly select 10 students. First, we need to assign digits to students that have blue eyes and students that do not have blue eyes. If we were to use single digits to represent both, which of the following would be a correct method of assigning these digits?

A. blue eyes: 0, 1 other: 2, 3, 4, 5, 6, 7, 8, 9
B. blue eyes: 1, 2 other: 3, 4, 5, 6, 7, 8, 9, 10
C. blue eyes: 1, 2, 3 other: 3, 4, 5, 6, 7, 8, 9, 10
D. blue eyes: 0, 1, 2 other:

Question

Of all the students in a particular class, 20% have blue eyes. We want to run a simulation to predict how many blue eye students will be chosen if we randomly select 10 students. First, we need to assign digits to students that have blue eyes and students that do not have blue eyes. If we were to use single digits to represent both, which of the following would be a correct method of assigning these digits?

A.	blue eyes: 0, 1 other: 2, 3, 4, 5, 6, 7, 8, 9
B.	blue eyes: 1, 2 other: 3, 4, 5, 6, 7, 8, 9, 10
C.	blue eyes: 1, 2, 3 other: 3, 4, 5, 6, 7, 8, 9, 10
D.	blue eyes: 0, 1, 2 other:

Since the differnece between blue eyes is whether someone has them or has them not, it's represented with 2 distinct numbers. The quetstion asks for single digits, so any set with '10' is incorrect.
