What is the probability that, when three twelve-sided dice are rolled, at least one 1 is rolled?  Choose the correct option:
A) 1/4 B) 3/144 C) 1331/1728 D) 23/144 E) 397/1728
Odds of no 1's: (11/12)^3 = 1331/1728   So the probability of at least one 1 is (1 - 1331/1728) = 397/1728, so the answer is 397/1728.
