Answer: 20/n
Hwy friend
Let's figure this out.
5+7+4+4= 20 total students
4/20 students have hazel eyes
6/20 students do not have hazel eyes
16 / 20 =.8
80% chance that 1 is not hazel
80% that the 2nd isn't hazel
To find the probability that both will not be hazel you must multiply:
80% by 80% (.8 * .8)
.8 *.8 = .64
There is a 64% chance both of the selected students wont have hazel eyes.
