Most have answered so far are operating under the idea that there are only two genes that determine eye color, one from mom and one from dad. This is FALSE! Pigmentation of hair, eyes, and skin are known as polygenic, meaning that there are multiple genes involved. Which genes are "active," how close they are to each other, etc affects the amount of melanin or pigment your body makes in different areas.
Blue and the variant grey are the "default" so to speak. What changes our eye color is the amount of melanin present in the iris. Green eyes have a small level of melanin which blends with the blue to create the appearance of green. Hazel has more melanin than green but not enough to make the eyes a true brown. Brown/black eyes have the most melanin.
Let me give you a real life example of just how complex eye color can be. My mother has green eyes and my father has brown eyes. They had 3 daughters. Their eye color in order of birth: Green, Blue, and Brown.
The ultimate answer to your question is Yes. It is possible for a couple with hazel and blue eyes between them to have a blue eyed baby. It may not be the most likely outcome but it is most certainly possible.

It is possible if the "hidden" gene for blue eyes has been passed down through generations from each side of the family.
If both the mother and the father give the baby their hidden genes, then the baby will have blue eyes.

If both parents have the recesive blonde gene then there is a 25% chance of their baby having blue eyes.
If only one parent has the recessive blue gene then it is impossible to have a child with blue eyes, that child however may be able to have a child with blue eyes depending if they have inherited the recessive gene and that their partner is also a carrier.

Brown eyes are dominant over blue eyes but if there is blue eyes in the parents' genes somewhere, it could be possible.

yes..
Hazel is a dominant gene when paired with blue
Brown is a dominant gene when paired with blue
So the child has a 25% chance of having blue eyes if the recessive gene is carried by both parents

Yes. The hazel and brown eyes are dominant to possibly some other colour, such as blue. So yes, it is possible.

Yes, it is possible.
I can't give you punet squares, statistics or anything else...except that I have brown eyes, and my wife has hazel eyes...and we have a son with blue eyes

Yes. The genetic factor affects our babies 6 generations back. So, don't be too surprised if your baby looks kind of different from the last 2-3 generations that you have seen. It's called recessive genes.

It all depends on your family histories. If somewhere in your family tree their is blue eyes, it would be very rare, but it is possible...

yes, especially if the milkman has blue eyes
