Answer:
B. 48
Step-by-step explanation:
We have been given data of scores of students in a Chemistry quiz. We are asked to find the range of the given data.
Since we know that range is the difference between highest and the lowest values of a data set. To find the range of our data set let us arrange our given data points in ascending order (least to greatest).
11, 22, 29, 30, 31, 32, 37, 41, 47, 48, 50, 59.
We can see that lowest value of our data set is 11 and highest value of data set is 59. Now we will subtract 11 from 59 to find the range of our data set.
Therefore, range of our given data set is 48 and option B is the correct choice.

Step-by-step explanation:
We solve building the Venn's diagram of these sets.
We have that n(S) is the number of succesful students in a classroom.
n(F) is the number of freshmen student in that classroom.
We have that:
In which n(s) are those who are succeful but not freshmen and are those who are succesful and freshmen.
By the same logic, we also have that:
The union is:
In which
