A student taking Management Science 301 at East Haven University will receive one of the five possible grades for the course: A,B,C,D, or F. The distribution of grades over the past two years is as follows:
A = 80 students
B = 75 students
C = 90 students
D = 30 students
F = 25 students
Total = 300 students
If this past distribution is a good indicator of future grades, what is the probability of a student receiving a C in the course?
