Answer:
as a fraction = 75/92
as a percentage = 81.52%
Step-by-step explanation:
total no of students = 92
probability that a student has hazel or brown eyes = Pr(hazel or brown)
but probability of a or b happening ie Pr(a or b) simply is Pr (a) +Pr (b)
therefore Pr(hazel or brown) = Pr(hazel)+ Pr(brown)
Pr(brown) = (no of brown eyes )/(total set of eyes)
= 
= 10/23
Pr( hazel) = (no of hazel eyes )/(total set of eyes)
= 
=35/92
hence Pr(hazel or brown) = (10/23) + (35/92) =75/92
so there's 75/92 probability (or 0.8 out of 1 chance )to choose either hazel or brown randomly
There are two of theme dudgeon
When you cook, if you are in a race maybe if you need to star a project but have a small amount of time to complete it
9a-4+3a-33=23
9a+3a-29=23
+29 +29
9a+3a=52
-3a -3a
9a=52-3a
9a/9=52/9- 3a/9
a=52/9-1/3a
