You're assuming that this data set represents all of Mrs. Hassaan's pupils. Certain students could be missing from the histogram - for instance, there could be one or two students who missed the test, but for certain reasons will be taking a make-up exam. Their grade would not be recording in this data set, but they still contribute to the class size, and so would be unaccounted for here.
The first one is C and the second one is B
(On the far left, it says 140 at the top and then 5 to the left of 28)
The answer is 35, let me know if you can't read anything or have any questions. Hope this helped :)
