To find the mean of the grades, we need to add up all the grades and then divide by the total number of grades.
Adding up the grades: 45 + 56 + 64 + 64 + 72 + 76 + 77 + 82 + 94 + 96 + 99 = 825
Dividing by the total number of grades (11): 825 / 11 = 75
Therefore, the mean of the grades is 75.
The correct answer is b) 75.
