However, the probability of getting 5 (or any other number 1-6) on a die is 1/6. The either-or probability is found by adding the probability of individual events.

The sum of both dice = 5 can be obtained by

1, 4

4, 1

2, 3 or

3, 2

The probability of getting any one of these pairings is 1/36. Again, the either-or probability is found by adding the probability of individual events.

I hope this helps. Thanks for asking.
