Why is it impossible for a person with blood type AB to have a child with blood type O?

because type O (0 - zero) has no patterns, type A has A0 or AA pattern, type B has B0 or BB pattern and AB has AB pattern.
patterns are combined, so A + B = AB, A + A = B, B+B = B and AB + 0 = AB (no pattern means nothing :)). It is the reason why blood type 0 is so rare, A0 + 00 will create A0, that means blood type A.
Well, blood type 0 is not the most rare one... You know, when human is in uterus, the whole evolution is taking place. If something goes wrong, ppl can be born with animal blood as well, eg I have blood type C.
EDIT
ABO blood typing is simple. A and B are co-dominant genes, and O is recessive. So, A and B rule over O. Type A blood means that your alleles (only one can come from mother and one from father) are either AA (alleles as a pair are called genotype) or AO (type A because the A is dominant over the O) but to be type O, you need to O alleles, or OO genotype, each parent mathematically has to have at least 1 O allele. The parent with AB doesn't have the O gene.

Can 2 blood type o parents have a child with type a?
the answer is no .. its just impossible
Can 2 parents with type o have a child with a- blood?
the answer is no .. its just impossible
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 an O neg mother and an A neg father produce a child that has AB blood type?
No, This is impossible!
Is there a website where you type in what type of person you want drawn and it has it there for you?
Can a man with blood type AB and a wife with blood type AB produce a child with blood type A
Can two parents with O positive blood have a A positive child?
No, it is impossible to get an A-type from two O-types.
Could a type B child with a type A a mother have a type A father?
no. because if the child's blood type is B, one of the parent must have type B or type AB but non of them has it. so it is impossible for the father to have typeA.
Can a person that has o positive blood and a person with a positive blood make a child that has a negative blood?
CAN TWO POSITIVE BLOOD TYPES MAKE a negative blood type
Can you have a baby with blood type A plus and O plus?
A person cannot have blood type A and O at the same time. Although they can have one allele for each, Ao - but this person would have blood type A. If you are asking whether a mother and father with types A+ and O+ can have a child, the answer is yes. This child will be either type A or O depending on the genes of the parent with type A blood.
Can O plus B produce O type blood?
Yes. There are two possible genotypes for a person with type B blood: BB or BO. If a person with the BB genotype has children with a person with type O blood, then all of their children will have type B blood. But, it the person has the BO genotype, then any child they have will have a 50% chance of having type O blood.
If a person with blood type o mates with a person with blood type b what are the possible blood types of their children?
The child will most likely be type B (genotype BO), however if the B parent is type BO, the child may be type O.
Can o positive parents have a child with blood type a positive?
No. Type O blood is a recessive trait. If both parents have type O then they are not carriers for type A, type B, or type AB. It would be impossible for their offspring to have any other blood type than type O.
