Question

In a genetics class, 6 students have GREEN eyes, 3 students have BLUE eyes, and 11 have HAZEL eyes. If a single student is picked at random, what is the probability that their eyes are GREEN or HAZEL?​

Answer 1

85%

6 students have green eyes = 6/20 = 30%

11 students have hazel eyes = 11/20 = 55%

20 = number of students

So 6/20 + 11/20 = 17/20 = 85%

Answer = 85%
