The odds are exactly 50/50 if the blue eye recessive allele exists in both gene pools. Green on the other hand will not occur; The children will only have blue or brown eyes.
Take a look at the illustrated chart below.

Punnett square =D brings back memories srry but i dont know how to illustrate this but if you know how to set up a punnett square (im assuming Brown eyed is BB and blue eyed is bb) so of course BB on top and bb on left or right, its bassicaly like tic-tac-toe after that and if you do so you will notice that they all are Bb so most likely they will be Brown eyed with a 25 overall percentage that one of them will be blue eyed
