it actually depends on the genotype of the parents because it can be AA or AO, and in the latter case it would manifest as A since it O is a recessive gene. so if both parents have AA, then there is no chance that the child will have blood type O. if, on the other hand, the parents have AA and AO, then the probability of having a child with blood type O is still zero. however, if both parents have AO genotypes, then the probablity of having a child with blood type O is 1/4.
the plus sign after the letter of the blood type is actually another classification of blood type. based on this classification, you can either be Rh+ or Rh-. for example, if you are O+, that actually means, you have blood type O and you are Rh+.

The question doesn't include enough information to give a positive answer. If both parents are type A, then either or both of them could be either homozygous for A (AA), or heterozygous A (AO). If one or both of them are homozygous, the probablility of having a child with type O is 0. But if both the parents are heterozygous A, then the probability of a type O child is 1 in 4.

Almost everyone is incorrect. In blood type, O is recessive. So if both parents are AO (which is often shortened to just A type) then there is a 1/4 chance the child can be type O.
I forgot to mention the rhesus factor is a completely independent allele from blood type. So + parents would also be able to have a + child.

I don't think there is any probability that a child with A+ parents will be O+. My husband and I are both A+ and all three of our children are the same.

they might get type-O+ for their child (the reason was given by few posts before me). but the child wont get O- unless one of the parents has a -ve.
