Answer:
The probability of a student receiving a C in the course is p=0.3.
Step-by-step explanation:
We have a absolute frequency for each of the grades (A to F), of a total of 300 course tests.
It is assumed that this sample gives a dood estimation of the distribution of the grades. Then, we can estimate the probability of obtaining a C in the course usign the relative frequency for C.
The relative frequency is calculated as the division between the absolute frequency (in this case, 90 for a C grade) and the size of the sample (in this example, 300).
![p_C=\dfrac{X_C}{N}=\dfrac{90}{300}=0.3](https://tex.z-dn.net/?f=p_C%3D%5Cdfrac%7BX_C%7D%7BN%7D%3D%5Cdfrac%7B90%7D%7B300%7D%3D0.3)
