The operative phrase in the OP is "'at least one of the dice is a 6.'", it doesn't matter which die is a 6.
But if we start not knowing if the red or green die, (for example,) is a 6, then we have 11 possible results at the early stage: (1,6),(2,6),(3,6),(4,6),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)
