Not a chance. First of all, ignore the + and -, it's not important in this case. Only the A, B, and O matter here for simplicity's sake. Each parent can only donate one allele to their child, hence, the parent with the co-dominant AB blood type could ONLY donate an A or a B to their offspring. A baby with the recessive OO blood type would have to have to have gotten one O from BOTH parents, which is obviously not possible in this instance. It's time to do a blood test on the milkman!

No. The AB phenotype means that the genotype is iAiB and that the child will receive either an A or a B in the gamete. The O phenotype means that the genotype is ii and therefore both parents have to have at least one i. Therefore an AB parent can not have an O child.

Impossible. The AB+ parent can only donate one of its two *** alleles. In this case, either an A or a B. Since the gene for blood type O is recessive, having either that A or that B would override blood-type O.

If you do a Punnett Square, the only possible outcomes are Ao, Bo, AB, and BB...so with the Ao and Bo, the o is the recessive component, so the A and B are dominant. O is not possible according to this method.

There is always a chance. Say mom is AB, while dad is BO (contains one copy of the B allele). It's possible that one of mom's gametes becomes mutated and becomes null, and mates with the 'O' type sperm. This would be incredibly rare, but is still possible.

No. Only A, B, or AB are possible.

That combination I do not think is possible. However with a question like that the answer can have severe consequences so I believe you should consult a professional and seek guidance.

If the mother is AB+, it's possible.
If the father is AB+, it's unlikely.

Who knows.
Only your doctor. Ask him.
