Question

Mrs ameldos class has 6 students with blue eyes 7 with brown eyes 3 with hazel eyes and 2 with green eyes. Two students are selected at random. Whats the probability of two not hazel?

Answer 1

We know that the probability of an event happening is:

$P=\frac{\#\text{ of ways it can happen}}{\text{Total \# of outcomes}}$

There are:

6 Students with blue eyes

7 students with brown eyes

3 students with hazel eyes

2 students with green eyes

The total of outcomes would be the total of students= 18 students

The percentage of choosing two students who do not have hazel eyes is: 83.3%

$P=\frac{6+7+2}{18}\times100=\frac{15}{18}\cdot100=\frac{5}{6}\cdot100=83.3$
