 Probability-and-statistics/323553: Two dice are rolled and one letter is chosen from a, b or c. Use the counting principle to determine the number of possible outcomes. 1 solutions Answer 231518 by Fombitz(13828)   on 2010-07-18 23:29:01 (Show Source): You can put this solution on YOUR website!Rolling two dice gives you 36 possible outcomes. So for each letter choice you'd have 36 possible outcomes. Since there are 3 letters that would make 3*36 or 108 possible dice/letter outcomes.
