Larissa rolls two number cubes, each with a number one through six Larissa adds the numbers that appear on the roll. which two sums have an equal chance of occurring?

2 and 12 have same chance of occurring

3 and 11

4 and 10

5 and 9

6 and 8

Each pair has same occurrence chance

Step-by-step explanation:

Here, we are interested in calculating knowing the sums that have an equal chance of occurrence.

Firstly, we need a sample space. A sample space refers to the set of all possible results.

Please check attachment for this

From the sample space we have 36 results;

Let’s list the outcomes and the number of times they all appear;

1- 0

2- 1

3- 2

4-3

5-4

6-5

7- 6

8- 5

9-4

10-3

11- 2

12-1

From the above, we can see that;

2 and 12 have same chance

3 and 11

4 and 10

5 and 9

6 and 8
