All eggs are trays(A) + No tray is a white(E) ⇒ No egg is a white (E) + Some whites are ducks(I) ⇒ Some ducks are not eggs(O*). Hence conclusion I follow. No tray is a white(E) ⇒ Conversion ⇒ No white is a tray(E). Hence conclusion II follows. Some whites are ducks (I) ⇒ Conversion ⇒ Some ducks are whites(I). Hence conclusion III does not follow.
