Only a few Engineers are Doctors (I) + Some Doctors are not Trainers (O) → Probable conclusion → Some Engineers may be Trainers (I). Hence conclusion III follows. A few Doctors are Lawyers (I) + No Lawyers are Trainers (E) → Some Doctors are not Trainers (O) → Probable conclusion → Some Doctors may be Trainers (I). Hence conclusion IV does not follow.
