Relative Frequency in Probability

There are $35$ students in a university class.

At the end of the semester an exam was conducted and the results are shown in the following table:

We are asked to complete the last line of the table representing the relative frequency of each grade.

We do this by dividing the frequency of the grade (number of students who received that grade) by the total number of students (in our case $35$).

For the grade $40$: the relative frequency is $\frac{1}{35}$

For the grade $50$: the relative frequency is $\frac{4}{35}$

For the score $60$: the relative frequency is $\frac{12}{35}$

For the score $70$: the relative frequency is $\frac{13}{35}$

For the grade $80$: the relative frequency is $\frac{2}{35}$

For the grade $90$: the relative frequency is $\frac{2}{35}$

For the grade $100$: the relative frequency is $\frac{1}{35}$
