IF the mother is the B-, there are potential health problems for the baby unless it's her first. make sure she gets the rhogam shots to prevent future babies from miscarrying.
are they homozygous A and B or heterozygous?
here are the possibilities:
AA+ X BB- = AB + or - (the Rh factor does have a recessive component that can express but most likely the baby would be a +).
AO+ X BB- = AB+/-, BO+/-
AA+ X BO- = AO+/-, AB+/-
AO+ X BO+ = AB+/-, AO+/-, BO+/-, OO+/-
interesting facts:
"AB+" is the universal receiver - we can receive blood from anybody at all. of the 4 main groups, AB is the rarest
"OO-" is the universal donor - they can give blood to anybody at all.

Threenor is correct, but to explain all those letters:
Each parent brings two alleles to the equation. And we don't know the full, double-lettered phenotype of either parent: you haven't supplied that information. Therefore, this couple's baby could have any one of the four ABO bloodtypes: O, A, B, AB, and we can't tell you the chances of its being any one of these. Sorry.
