 P: 15 1. The problem statement, all variables and given/known data 12 different dice are rolled. How many outcomes will have at least one of each number 1,2,3,4,5,6 occurring? 3. The attempt at a solution I dont even know where to go because I really dont know what the question is asking. Does it mean how many rolls (where each roll is rolling 12 dice) must be made to get at least one of each number? Thanks
 P: 147 You roll 12 dice. Each (standard) die has 6 sides. You roll one die, it has 6 different outcomes. You then roll the second die, it has 6 outcomes. For the first two die, you could have 1-1, 1-2, 2-1, 2-2, 3-1, 3-2, 3-3, 2-3, 1-3, etc. So, after rolling all 12 dice, you have 12*6 possibilities in total. In how many of those possibilites will you have at least one die being a 1, one being a 2, one being a 3, 4, 5, 6..?
 P: 253 It seems to me like a probability question... Since there are six numbers possible on a dice, and you have have 12 dices, the chances for any of those numbers(1,2,3,4,5, or 6) to come on a single dice is 1/6(<-- fraction). Can you figure out the rest?
