so this is more of a pedantic question..


the question asks, "what is the likelihood of the couple's son will have have hemophilia?"



so the question is already assuming the child is a male, thus there should be no need to * 1/2 to account for the probability of gender.


however, the solution does * 1/2 to account for P of gender.


I think it would make more sense to do the latter if the question stated, " what is the likelihood the couple have A son that has hemophilia?"


thoughts?

Yeah I remember getting this question wrong because of the wording. When Bootcamp asks similar questions they also multiply by 1/2. So I would say always do *1/2 when it’s gender specific
