Question

What is the probability of rolling a sum of 12 on a standard pair of six-sided dice? express your answer as a fraction or a decimal number rounded to?

Answer 1

1/36

Explanation:

Each dice can take 6 values and if we roll two dices the values are independent from each another. All the possible combinations are 6 × 6 = 36.

There is only one way of rolling a sum of 12, which is that each dice takes the value 6.

The probability of rolling a sum of 12 is:

`P(12)=(favorable\ cases )/(possible\ cases) =(1)/(36)`
