    Yes it is possible

    Explanation:

    I cannot get you a punnet square but ...

    Mother: Type A blood = 1 part A blood 1 part O blood = OA

    Father: Type B blood = 1 part B blood 1 part O blood = OB

    There is a 25% chance for O blood

    There is a 25% chance for AB blood

    There is a 25% chance for OB blood

    There is a 25% chance for OA blood
