What is the best way of answering this question?

Do i diagram it? I tried to and came up with this: "Most of the students who took Spanish 101 at the university last semester attended every class session" STS101-most-ECS (ECS-some-STS101) "However, each student who received a grade lower than B minus missed at least one class session." RGLB- ----> M1+ (not M1+ ---> not RGLB) How do you diagram and solve this? Really confused. Thank you!

Hi, I don't think I would diagram this. I would, however, think about what these two statements mean and try to out them together. We know that if you got a low grade, then you missed a class. This also means that if you did not miss a single class, you did not get a low grade. We also know that the majority never missed a class. We can put these two statements together to know that the majority did not get a low grade. Diagraming the S/N statement, and particularly taking it's contrapositive might be helpful, but it is not a must.
