Answer:
there is no probability of complete affected daughter.
Explanation:
Hemophilia A is a rare X- linked disease. it is a recessive trait so only affects females when present in both X chromosomes, however, in males, there is only one x chromosome present and its enough to affect the individual.
As stated in the question that one son diagnosed affected, it is only possible when the mother is a carrier for this disease, and if the mother is a carrier then the daughter will be carrier too as it is X-linked recessive trait. So the probability of daughter with hemophilia A is none but could be a carrier.
