1/36
The probability that you roll a 3 or a 5 on one or both dice is 20/36 = 5/9
The answer depends on what sort of dice you roll and how many.

There is 4 ways to roll a 9 with 2 dice, and 36 possible outcomes. So, the probability of rolling a sum of 9 with two dice is 4/36 or 1/9.

1/36
The probability of rolling a 7 with 2 dice is 6/36; probability of rolling an 11 is 2/36. Add the two together to find probability of rolling a 7 or 11 which is 8/36 or 2/9.
In this case, you should first calculate the probability of NOT rolling either a 3 or a 6. For one die, this probability is 4/6 = 2/3. For two dice, this probability is 2/3 x 2/3 = 4/9. Therefore, the probability that you DO get a 3 or a 6 is 1 - 4/9 = 5/9.
The probability that you roll a 3 or a 5 on one or both dice is 20/36 = 5/9
I suppose you mean, at least one of those numbers. Just calculate the probability of NOT getting any of those, and take the complement. The probability of not getting a one nor a five on a single die is 4/6 or 2/3. For two dice, the probability is 2/3 x 2/3 = 4/9. So, the probability of getting at least a one or a five with two dice is 1 - 4/9 = 5/9.I suppose you mean, at least one of those numbers.

1 - 8/36 = 1 - 2/9 = 7/9
The probability of rolling a sum of 5 with two dice is 4 in 36, or 1 in 9, or about 0.1111. 1 and 4 2 and 3 3 and 2 4 and 1
The probability is 25/216 = 0.1157, approx.
