Dice vs Die:

The word "dice" is plural. So rolling "twice" means you are rolling the pair twice. The probability that one pair will NOT be 12 = 35/36. The probability that you will get at least one 12 in 2 rolls is 1 - (35/36) * (35/36) = .054784

well the first roll result can be anything in case the second roll is 12 and vice versa.
so (1 * 1/36 )*2=0.0556 .
