The probability of rolling more than a six with one roll of a cube whose sides are marked from 1 to 6 is zero.
If you roll a pair of six sided number cubes the probability of rolling two numbers whose sum is 6 is 5/36 or 0.1389. There are 5 ways to get 6: 1,5 & 5,1 & 4,2 & 2,4 & 3,3. There are 36 outcomes for a roll of 2 dice.
Total number of outcomes are 6*6 or 36. There is 1 way to get a 2; which is 1,1. So, the probability is 1/36.
With two tetrahedral dice labelled 1-4 the probability is zero as the maximum score possible is 8.With two cubical dice labelled 1-6, the probability is 6/36 = 1/6Other d&d dice (d8, d10, d12, d20) are left as an exercise for the reader.
The probability of rolling doubles on a pair of dice is 1 in 6, or about 0.1667.
The first step is to determine what the experiment is: rolling a pair of dice, drawing two cards from a deck of playing cards, selecting numbered cards?
It would be possible to find two numbers whose sum is 7, two others whose difference is 7,two others whose product is 7, and two others whose quotient is 7.But if you're looking for numbers that equal 7, then 7 is your only choice.
The sample space has 36 elements (the total number of outcomes by rolling the two dice). There are 6 double outcomes: (1,1), (2,2), (3,3), (4,4), (5,5) and (6,6). There are 5 outcomes whose sum is 6: (1,5), (5,1), (2,4), (4, 2), and (3,3). The probability of rolling doubles OR the sum of 6 is 6/36 + 5/36 = 11/36.
It's quite possible to find two numbers whose sum is 308, two others whose differenceis 308, two more whose product is 308, and another two whose quotient is 308.But if you're looking for numbers that equal 308, then your only choice is 308 .

A mathematical sequence whose verb is equal is the definition for an equation. An equation is given in the form A is equal to B. An equation can contain numbers and variables.
