Juanita Has Taken Six Courses at Valley Community College, and She

Short Answer

Juanita has taken six courses at Valley Community College, and she has a grade average of B so far. All the courses she has taken have been in sociology and psychology. She's thinking of enrolling in another course next term, and she expects to make at least a B in whatever she takes. If we don't know yet what subject she will take, would her argument be stronger, weaker, or neither if her previous six courses had been in four different subjects rather than two?
