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.
The probability of rolling doubles on a pair of dice is 1 in 6, or about 0.1667.
The probability of rolling more than a six with one roll of a cube whose sides are marked from 1 to 6 is zero.
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?
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.

For 6 sided dice, there is only 1 way to get a 2: (1,1). There are 36 outcomes rolling 2 dice; so the probability of rolling two numbers whose sum is 2 is 1/36.
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.
The probability of rolling doubles on a pair of dice is 1 in 6, or about 0.1667.
The probability of rolling more than a six with one roll of a cube whose sides are marked from 1 to 6 is zero.

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.

The answer is: 3
You can 'factor' a number to find the numbers whose products make that number.
There are no two numbers whose product is 23 and whose sum is 10. 23 is a prime number, and the only numbers whose product is 23 are 23 and 1. A prime number can only be divided by itself and 1.
