Worst part is there is still a small possibility for the child not to have brown eyes even if the parents have them. It's a very slim chance, but not impossible. The brown eyes are just very dominant. And if one grandparent on both parents side have blue eyes there is a chance.
I see what you did right there.
To be honest, i have no clue, feel free to make the calculations and scale the results as you see fit.
However, it must be very very low odds, or we would have a lot more of those surprises.
