No children will have short eyelashes. Chance or probability is "0".

Explanation:

Father - dominant long - LL

Mother -recessive -short - ll

So, their children will get "L " from the father and "l ", from their mother.

Genotype of the children is Ll, and phenotype is long eyelashes.

So, no children will have short eyelashes. Chance or probability is "0".
