2 dice each dice has 6 numbers how many combinations could there be?
There are 21 combinations.
If two dice are rolled what is the probability of rolling two different numbers?
15/21= 71.43% chance. It's the number of possible throws without repetition divided by the total different combinations of dice throw. Here is a handy Combination and Permutation Calculator: http://www.mathsisfun.com/combinatorics/combinations-permutations-calculator.html
Using 2 dice is the most likely number to roll?
There are 21 possible combinations of 2 dice. The total with the most possible combinations is 7, which has three. (6+1,5+2,4+3) This is not right. By this logic 6 and 8 have equal chances of being rolled as I can roll a six through the numbers, 5-1, 4-2, 3-3. When counting the probability of a number to be rolled you have to assume the dice do not care the order in which they are rolled. That is to say, a roll of 5-2, and 2-5 are NOT the same. It is for this reason we find that 7 truly has many more ways a being rolled. 2-5, 5-2, 6-1, 1-6, 3-4, 4-3. While both 6 and 8 have less because one of their dice rolls cannot be counted twice the double roll. For six this is the 3-3 roll, and for eight its the 4-4 roll. That is why 7 is the most common roll on two dice.
If a pair of dice is rolled how many ways are the two numbers different?
If the order of the dice is irrelevant, then the answer is 21. If the order of the dice is relevant, the answer is 36.
Have two dice from numbers 1 - 20 what is the most likely to be rolled?
-19
