If the female has what is classically defined as female hemophilia (carries the mutation on both of her X chromosomes), then all sons she would have would also have hemophilia. All of the woman's daughters would also inherit the gene, however since they would also be getting a normal X chromosome from their father, they would not, themselves, have hemophilia under the classical definition.
Today, it is understood that even carrying the trait on a single X chromosome can reduce a female's factor levels and give cause for doctors to diagnose her with hemophilia. Thus if you are simply looking at genetics (which you probably are) then the answer is all of her sons would have it and all of her daughters would be carriers. Therefore, since there is a 50-50 chance the first child bore would be a male, and a 50-50 chance it would be a female, the chance that their first child born would have hemophilia is 50%.

A woman with hemophilia and a man without hemophilia get married. What are the chances that their first child will have hemophilia?
There is no chance that the child will have hemophilia even if the spouse has hemophilia. Any girls the couple has will be carriers if the spouse has hemophilia.
A man with hemophilia marries a woman without the disease What is the possible offspring?
All Girls will be carriers of Hemophilia. All Boys will be unaffected (they won't have Hemophilia).
A woman is a carrier for hemophilia what is the chances for sons with hemophilia if the father does not have hemophilia?
There are no hard answers to this, it depends strictly on luck. The statistics are though not very good for their children. Statisically the couple have a chance of having a normal son, a daughter that is a carrier for hemophilia, a daughter with hemophilia and a son with hemophia.
What are a woman chance of being a carrier for hemophilia if she phenotypically a normal woman and has phenotypically normal parents but has a hemophiliac brother?
She has 1/2 chance. We can figure out exactly what her parents' genotypes were. Her brother has a Hemophilia allele that he got from his mom. So their mom has at least 1 Hemophilia allele. If she had 2 then she would have Hemophilia. The father cannot have a Hemophilia allele because it would have been expressed. So her chances are 1/2 because her mother has 1 Hemophiliac and 1 normal allele.
What is true of a woman with the genotype?
She is a carrier of hemophilia but does not have the condition
If you know a woman has hemophilia what can you infer about her parents genetype?
Her father has to have hemophilia as well, and the mother is a carrier or also has hemophilia. So if we pretend that the hemophilia gene is "x", you need to have "xx" to have hemophilia. The father must have the genotype "Yx" and the mother has the have "Xx" or "xx".
True or false woman can be born with hemophilia?
It is possible but extremely rare.
What gene does hemophilia affect?
The gene that causes hemophilia is located on the X chromosome. A woman who gives birth to a child with hemophilia often has other male relatives who have hemophilia. Sometimes, a baby will be born with hemophilia when there is no known family history. This means the gene can be"hidden"( or passed down through several generations of female carriers without affecting any male members of the family) or the change in the X chromosome is new (a spontaneous mutation).
Who can inherit hemophilia?
Anyone can inherit hemophilia. In most cases, it is a man whose mother is a carrier of the disease. It is extremely rare for a woman to have hemophilia but it is not uncommon for one to be a carrier. It is even possible for someone whose family has no record of hemophilia to get it through gene mutations.
