Yes, consider this using Punnett sqare method.
AB crosses with O to give these possibilities:
50% chance of child w/ A blood
50% chance of child w/ B blood
No chance of O due to o is recessive.
Hope this helps.

You don't have enough info about the positive or negative, but it's possible for her to have a Type A child in this case.
Mom has these alleles (forms of the gene): A and B
Dad has these alleles: O and O
Child could get A from Mom and O from Dad = AO.
AO is Type A blood because A is dominant to O.
Incidentally, the child could also be type B = BO.

Types AB and O can have a Type A child. As for the Rh factor, I don't know for sure, both because Wikipedia's entry for it is complex and because you didn't list the parents' Rh types, but I think Rh- is recessive, so any combination of blood types could have an Rh- child.
Short answer: Yes.

yes. Her genotype is AB and the man's is ii (Type O).
i i
A Ai Ai
B Bi Bi
The genotype for type A blood is Ai. The man can only give the i gene, so it depends on which gene the woman gives whether the child has type b blood or type a blood.
sorry if that punnett square is a little messed up.

Okay, the Rh factor has nothing to do with the problem.
The mother would give A or B type, the father would give out o or o. The choices are Ao or Bo. So, yes to your question.
Now for the Rh, if the mother is negative, the child may be positive or negative, depending on the father.

Yes. If the gamete of the mother with the A allele and the the gamete of the father with the O allele meet, then the child will have the genotype AO. Hence, his blood type will be A.

Yes. Depends on the grandparents on both sides. Mother has A & B and father has O which is universal but recessive so no O but A and B are possible. Rh factor can be either + or -

no the child has to have one of the parents blood types.
