We can make a chart for all the sums:

 

2 3 4 5 6 7 8 9 10 11 12
1 2 3 4 5 6 5 4 3 2 1

(The first row is the sum, and the second is the number of ways to get that sum)

 

So as you can see in the chart, the possibilities for rolling a sum of \(5\) is \(4\), and the number of possibilities for any sum is \(36\). This means that your probability would be \(\frac{4}{36} = \frac{1}{9}\).
