They don't HAVE to - it's just the way dice have always been marked. You could have a dice that has 6 & 5, 3 & 4 and 1 & 2 on opposite sides - it would still be a dice but wouldn't follow the 'opposites total 7' rule.
The dots on a pair of standard six-sided dice can add up to a total ranging from 2 to 12. The minimum sum of 2 occurs when both dice show 1, while the maximum sum of 12 occurs when both dice show 6. The average sum of two dice is 7.
42, 63, 84 and 105.
There are eleven possible "sums of dots" if you throw two 6-sided dice. The range of possible values is from 2 (1+1) to 12 (6+6).
1/4
The sum can be any number from 2 to 12.That's 11 possible outcomes.
2/9!
A standard six-sided die has faces numbered from 1 to 6. The sum of the dots on all the faces can be calculated by adding these numbers together: 1 + 2 + 3 + 4 + 5 + 6, which equals 21. Therefore, the sum total of the dots on a single die is 21.
never.. the highest number on a dice is a 6
It is 6/36 = 1/6.
Prob = 4/36 = 1/9
Yes, quite easily.
It is 30/36 = 5/6
