Can two parent with A and a parent with AB positive and have O negative baby?
No.
Can parents who are AB negative and O negative have a B positive child?
Yes, if the AB parent contributes a B allele, and the O parent contributes an O allele, then the child will be BO, and will have type B blood.
Can an O-positive father and a B-negative mother have an AB-negative child?
No, an O-group parent cannot have an AB-group child at all.
Can a o positive and a b positive have a ab negative?
No, an O-group parent cannot have an AB-group child at all.

because the dad blood was stronger and one positive and one negative make a positive
Can an o negative mother parent a B negative child?
Yes, if the father has type B or AB blood.
Can a o positive father have an AB negative child?
No. In order for someone to have AB blood, they must inherit the A from one parent and the B from the other. Therefore a parent with O blood could only have A, B or O children (depending on the blood type of the other parent).
If one parent has ab positive and one parent has o negative what type of blood will the baby have?
The baby could have almost any bloodtype except for O.
Can an A-positive and a O-negative have a B-positivechild?
No. Neither parent has the B antigen. Only the O antigen can be "masked" by another; if A+ parent had the B gene they would be AB+, if O- parent had it they would be B-.
