It is possible, however it is extremely rare.
I'm not sure how 'rare' it is though since there are 3 of us with Blood Type O born to an AB Blood Type mother and an O Blood type father. We are not of European/Asian descent either.
From what I've learned, there are different ways this can happen. One is called the Bombay blood type. Chimera blood type is another.
In certain Asian groups, some of these folks have a rare version of the ABO blood type gene called cis-AB. People with this gene version have an AB blood type but can easily have an O child.
So it is possible. 'How', I'm trying to figure out myself.
What else can I help you with?
How can a child that is born with type AB blood?
the child takes the A gene from one parent and B from the other. And the both of parent are supposed to be AB blood type, or one A blood type and the other B.
Could a parent with AB-blood type have a child with O-blood type?
No.
If you are AB plus can your child have the same blood type as you?
The child can have the same blood type. It is possible if the child obtains the allele IA from one parent and IB from the other. So if a person with blood type AB provides IA or IB and the other parent provides the other allele, then the child may have the same blood type i.e. AB positive.
Can b positive parent have child with a positive blood?
A B+ parent can have a child with A+ blood. The other parent must be type A or type AB for this to occur.
Can a child with blood type O have a parent with AB blood type explain?
No. A and B are dominant blood types and O is recessive. A parent with blood type AB can only donate a dominant A or dominant B. A child with blood type O would need to come from parents with one of the following combinations: A-A, A-B, A-O, B-O, O-O
Can parents with AB blood type have a child with O blood type?
"No, if each parent has AB then the child can be A, B or AB but not O." Not exactly. Yes, it IS possible for a child with Blood type O to have a parent with the AB Blood type although it is extremely rare. There are different reasons for this. One is the Bombay blood group. There is also Chimera, or 'vanishing twin'. In certain Asian groups, some of these folks have a rare version of the ABO blood type gene called cis-AB. People with this gene version have an AB blood type but can easily have an O child. I am an O blood type child of an AB blood type parent, although we are not of Asian/European descent. I also have other siblings who are Blood type O so I know it is possible.
Can a child with type o blood have parents with ab blood?
"No, if each parent has AB then the child can be A, B or AB but not O." Not exactly. Yes, it IS possible for a child with Blood type O to have a parent with the AB Blood type although it is extremely rare. There are different reasons for this. One is the Bombay blood group.

I also have other siblings who are Blood type O so I know it is possible.
If one parent has AB-blood type and the other has O-blood type what blood group will their child have?
Either A or B; AB and O are impossible.
Can parents both blood type b positive have a child with a blood type?
No. B type can only have B, O, and AB. A child with A blood would have to have at least one parent be A or AB.
Can an O positive blood type parent produce an AB negative blood type child?
yes
Can you be the father if the baby don't have mine nor the mother blood type?
Yes. A mother with blood type A (AO) and a father with blood type B (BO) can have a child with blood type O (OO), one O from each parent. An AB parent and a A (AO) parent can have an B child (BO), an AB and a B (BO) can have an A (AO). An AB parent can never have an O child because it requires two recessive genes and an AB parent cannot donate a recessive O.
Can an A negative parent and a A positive parent have a child who is AB negative blood type?
it can be rare only
