Is it possible for one child to have cystic fibrosis while another, from the same parents, be completely normal?

In brief: Yes

The child would need to inherit an abnormal gene from both parents.
So, the chance of the child having CF is 25%.

In brief: Yes

The unaffected carrier parents of a CF kid can produce 3 possible genetic combinations in their kids.
CF with 2 abnormal genes(one from each).A normal kid with normal genes (one from each parent). An unaffected carrier (one abnormal and one normal gene). There is risk of CF with any conception, but any combination is possible.
