A normal man and a heterozygous color blind "carrier" woman have a baby. If they have a girl, what is the probability that the girl will be colorblind. If they have a boy, what is the probability that the boy will be colorblind?

PsyDAG,
First of all, carriers do not show the effects in their phenotype, so she cannot be colorblind.
You can do a Punnett square to find your answer.
However, to save you some time, the probability is 50% in both cases.
