Answer 2

Your Question?

Answer 3

Since, it doesn't state that the 14 or 19 or 6 students are studying psychology out of the 28 psychology students, we could assume that each group is separated from each other, therefore I think the amount of students that are taking psychology only is 28. (I'm not sure if 28 is the answer, I'm assuming it is.)
