Students who enrolled in atleast one of the classes = 50 - 6 = 44

Students who enrolled in both of the classes = 32 + 37 - 44 = 25

Students who enrolled only in psychology = 32 - 25 = 7

Students who enrolled only in logic = 37 - 25 = 12

Total number of students who enrolled only in one class = 7 + 12 = 19
