two dice are rolled find the probability of getting a 5 on either dice or the sum of both dice is 5

However, the probability of getting 5 (or any other number 16) on a die is 1/6. The eitheror 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 eitheror probability is found by adding the probability of individual events.
I hope this helps. Thanks for asking. 
10/36
