No it is not possible as the parent will transfer either Ia or Ib antigen to its progeny so whatever be the genotype of other parent the offspring can not have an O blood group( O blood group is recessive)

Since both parents have AB blood group their genotypes will beIAIB.On the other hand O blood group being a recessive trait, can be expressed when the genotype of the person is IOIO.But here the child cannot inherit Ifrom either of the parents.So O blood group is not possible.
