If a child's mother has blonde hair and blue eyes, and the father has black hair and brown eyes, how likely is it that the child would have blonde

There is no dominant gene:homologous pairs of chromosomes are arranged randomly during sexual reproduction, you cannot tell which genes will be more dominant but the child will have the same amount of genetic info from each parent.

My father has blond hair ,blue eyes and fair skin, my mother has dark hair, dark brown eyes and an olive complexion,: I'm a redhead with green/hazel eyes and white as a sheet🤷
