In humans, having dimples is dominant over not having dimples. If a woman without dimples marries a man heterozygous for dimples, what is the likelihood that their children will have dimples?

In cattle the allele for cloven hooves (H) is dominant over the allele for mule-foot hooves (h). The phenotype for each trait is shown in this picture. What is the probability of cloven hooves in the offspring of parents that are heterozygous for the trait?
