Explanation:
Detailed explanation-1: -The probability of scoring a sum greater than 9 or a doublet is =10/36=5/18.
Detailed explanation-2: -So the probability that the sum is going to be greater than nine or less than four, that is going to be five of our 36 Plus 3/36. And that gives us 8/36. And if we do the math we have to over nine. So the probability that the sum will be greater than nine or less than four is it goes to 2/9.
Detailed explanation-3: -The probability of getting 9 as the sum when 2 dice are thrown is 1/9.
Detailed explanation-4: -Explanation: If we’re talking about standard number cubes, then the maximum answer possible is 12 (=6+6) . Therefore, all possible rolls are less than 13, giving a probability of 100%.
