if a woman is a carrier for a disease (Hh) and a man has a 50% chance of being a carrier for that disease, what is the probability that they have a child with that disease?

i've figured out that if the man IS a carrier, there is a 25% chance and if the man IS NOT a carrier, there is no chance. but what is the overall probability?
