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

Answer 1

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.

Answer 2

10/36
