If the individuals can't roll their tongue, then the child won't be able to roll it's tongue. If they can roll their tongue, then the child will be able to roll it's tongue. it just depends.
It is always 50/50.

The sex of a child is determined by male sperm. There are only two sexes, so there is an equal (50-50) chance of having a boy or girl.
There is not enough information on the propensity for the parents to have a child of either gender and so it is necessary to assume that the probability of the gender of the next child is independent of the genders of preceding children. In that case the probability of the next child being a girl is 1/2.There is not enough information on the propensity for the parents to have a child of either gender and so it is necessary to assume that the probability of the gender of the next child is independent of the genders of preceding children.

The chance of the child having schizophrenia when both parents have schizophrenia is about 37%. There is no data available for other combinations of illnesses, for example if one parent has schizoaffective disorder and the other has schizophrenia.
Nowadays it is approximately 0.5169
The probability is zero! There is no such thing as "normal". Every child (and adult) has some unique characteristics and that makes them not normal - in that respect.
It's used commonly to estimate the traits of a child of two parents. For example, the probability of the child having blue eyes, or curly hair, or even having genetic disease.
Since having a child to a child is an independent event (assuming no outside intervention), the probability is still about 50 / 50 boy or girl.
It is always 50/50.

50-50. In the circumstances you list, each child of theirs has an equal chance of having- or not having- HD.
If they are expressing the trait, 100%, as their genotypes would be, rr X rr If they both carry the trait and it is dominated, Rr X Rr, then the probability would be, 25% of their child expressing the trait.
A yellow coating on a child's tongue could indicate a buildup of bacteria, dehydration, or poor oral hygiene. It's recommended to consult a pediatrician or pediatric dentist for a proper diagnosis and treatment.
