Answer:
75
Step-by-step explanation: Well, since you didn't say what fiction was, I have no way to confirm this, but if 36, 20, and 30 add up to 86, and I use 36 (comedy) and multiply it by the amount of students serveyed, I get 5,400. Devide that by 86 (the total of all servey) You get 62, and again, since I don't have the percent for fiction, I will have to say that it is most likely 75, due to that being the only number above 62.
Answer:
a) Suppose that F is ordered in ascending order: 
. Then, the complement of F can be written as
which is the union of a finite number of open intervals, then 
is an open set. Thus, F is a closed subset of the real numbers.
b) Take an arbitrary element of F, let us say 
. Now, choose a real number 
such that
there are not other element of F, because is less that the minimum distance between and its neighbors.
In case that 
we only consider 
, and if 
we only consider 
.
Then, all points of F are isolated.
