In a classroom of 20 students. 14 of them have brown eyes. If a teacher picks 2 students at random to pass out supplies, what is the probability she chooses 2 students without brown eyes?

Answer 1

6 of the 20 have other colors
6/20 for the first one
now you have 5 out of 19 left
so
6/20 * 5/19

Answer 2

consider this like selection without replacement. So, with 6 students without brown eyes, the probability of drawing two of them is
6/20 * 5/19

Answer 3
