Well, you failed to mention which one is the recessive trait in this instance. But, let’s say red hair is recessive, denoted by r and brown hair is dominant denoted by R. Mom is rr and dad is RR.

They will all carry the trait for red hair but will express brown hair themselves, so 0% probability of having a child with red hair from the initial parents
