In humans Bombay syndrome is a recessive allele in which homozygous recessive individuals do not display A or B antigens.  Two individuals, one who is homozygous for type A blood, and the other who is heterozygous for type B blood decide to have children.  Both are heterozygous for Bombay syndrome.  Based on this information, what is the probability that they will produce a child who is Aihh?

I don't know for sure if this is right. I haven't done probabilities for a long time. By doing a Punnett square, you'd see that with blood type possibilities, you'd have two squares resulting in Ai, so 50% of that. With the Hh genes, you'd have one of the squares resulting in hh, so 25%. I think you then multiply the percentages, giving you a 1/8 chance or 12.5%. That end result could be wrong, but the percent chance on Ai and hh are correct.
