What is the probability of rolling a sum of 2
on a standard pair of six-sided dice? Express your answer as a fraction or a decimal number rounded to three decimal places, if necessary.
The only way to roll a sum of 2 on a pair of six-sided dice is to get a 1 on each die. There is only one combination that results in this sum (1,1).
The total number of possible outcomes when rolling two dice is 36 (6 possibilities for the first die multiplied by 6 possibilities for the second die).
Therefore, the probability of rolling a sum of 2 is 1/36 or approximately 0.028 (rounded to three decimal places).
