Some plants are flowers (I) + [No petal are flowers (E) → Conversion] → No flowers is petal (E)  → Some plants are not petals (O). Hence conclusion II follows. Some plants are flowers (I) + [No petal are flowers (E) → Conversion] → No flowers is petal (E)  → Some plants are not petals (O) → Probable conclusion → All petal may be plants (I). Hence conclusion III follows.
