Transcript: Math Task Probability Dice Rolling 2 We know that the sum of all the numbers cannot exceed 12, because 6 (the highest number on the dice)+6=12. Using the same method, the sum must be larger than 2 (the smallest number on the dice is 1, and 1+1=2). Therefore, there are 11 possibilities for the sum of the two dice. ...and now for the math. There is only 1 possible way that you can get a sum of 2 when rolling two dice - snake eyes, or two ones. So what's the probability? As you can see above, you have the most chance of rolling numbers with a sum of either 6, 7, or 8. You have a less likely chance of rolling numbers that have a sum of 4, 5, 9, or 10, and an even less likely chance of rolling numbers with a sum of 2, 3, 11, or 12. Freedom to Explore With 2 Dice Possible Outcomes And so... 3 There are 21 possible combinations between the two dice (1 and 2 is the same as 2 and 1). That means that all fractions will be out of 21. In order to The probability of rolling numbers with a sum of 2, 3, 11 or 12 is 1/21, or 0.048% 1,1 3,3 1,2 3,4 1,3 3,5 1,4 3,6 1,5 4,4 1,6 4,5 2,2 4,6 2,3 5,5 2,4 5,6 2,5 6,6 2,6
