Question

26 sided dice are rolled. What is the probability of getting a sum equal to four? Type a simplified fraction or round the answer to two decimal places.

Answer 1

1/12

Explanation:

The probability of an event is:

p(event) = (number of desired outcomes)/(total number of possible outcomes)

When rolling two dice, there are 36 possible outcomes.

They are listed below.

1, 1

1, 2

1, 3

1, 4

1, 5

1, 6

2, 1

2, 2

2, 3

2, 4

2, 5

2, 6

3, 1

3, 2

3, 3

3, 4

3, 5

3, 6

4, 1

4, 2

4, 3

4, 4

4, 5

4, 6

5, 1

5, 2

5, 3

5, 4

5, 5

5, 6

6, 1

6, 2

6, 3

6, 4

6, 5

6, 6

The outcomes with a sum of 4 are:

1, 3

2, 2

3, 1

There are 3 desired outcomes out of a total of 36 possible outcomes.

p(sum of 4) = 3/36 = 1/12
