PLEASE HELP ASAP!!

Amy collected data to see if there is a relationship between students having blue eyes and students wearing orange on the day of the survey. She randomly surveyed the eighth grade class and the results are shown above.

what percentage of “not blue eyes” students were” not wearing orange”

A. 45%
B. 40%
C. 20%
D. 30%

Answer 1

To find the percentage,we need to form a fraction first:

The nominator would be: the students who have not blue eye and were not wearing orange at the same time (50)

The denominator: students with not blue eyes (20)

Hence we can form the fraction: 20/50

To find the percentage, we can multiply the fraction by 100%:

20/50x100%

=2/5 x 100%

= 200/5 %

= 40%

Therefore the answer is 40%.

Hope it helps!
