When you roll 2 dice, the number of possible outcomes is 6x6 =36.
From these 36 outcomes 3 are a 2 or 3 [(1,1), (1,2), (2,1)].
So the probability of getting a 2 or 3 is:
P(2 or 3) = 3/36 = 1/12 = 0.08333... ≈ 8.3%

If you roll two dice what are the odds that you get a one or a five?
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.

What is the probability of getting less than 10 when you roll a dice?
A die normally has six sides with the numbers 1 to 6 on them, so any roll will be less than 10 and thus the probability of getting less than 10 with a die is 1. With two normal dice, the sum of the digits on the dice added together ranges from 2 to 12 and the probability of getting less than 10 is the same as 1 minus the probability of getting 10 or more. There are 36 ways the two dice can fall and 10 can be achieved in 3 ways (4&6, 5&5, 6&4), 11 can be achieved in 2 ways (5&6, 6&5) and 12 in 1 way (6&6). Thus the probability of getting 10 or more with 2 dice is (3+2+1)/36 = 6/36 = 1/6 So the probability of getting less than 10 is 1-1/6 = 5/6
If you roll a number cube twice what is the probability of rolling a 6 and a 2?
Assuming that a dice roll is purely random, there is a 1 in 6 probability of landing on any number. Since the second roll depends on the probability of the first, they factor together: First Roll: 1/6 Second Roll: (1/6)(1/6) = 1/36 If you were rolling both dice at once, however, the math would be completely different.
What is the probability of rolling a sum of 8 on at least one of two rolls of a pair of number cubes?
The probability of rolling a sum of 8 on one roll of a pair of dice is 5/36.The probability of not rolling a sum of 8 on one roll of a pair of dice is 31/36.The probability of rolling a sum of 8 twice on two rolls of a pair of dice is(5/36)(5/36) = (5/36)2 .The probability of rolling first a sum of 8 and then rolling a sum that is not 8 on thesecond roll is (5/36)(31/36).The probability of rolling a sum that is not 8 on the first roll and rolling a sum of 8in the second roll is (31/36)(5/36).So The probability of rolling a sum of 8 at least one of two rolls of a pair of dice is(5/36)2 + (5/36)(31/38) + (31/36)(5/36) = 0.258487654... ≈ 25.8%.
What is the probability of getting 4 dots on top in rolling two dice?
The probability of rolling a 4 in a die is 1 in 6, or about 0.1667. The probability, then, of rolling a 4 in at least one of two dice rolls is twice that, or 2 in 6, or 0.3333. The probability of rolling a sum of 4 in two dice is 3 in 36, or 1 in 18, or about 0.05556.
What is the probability of rolling 2 dice and getting 2 sixes?
In one roll the probability is 1/36.
What is the probability of getting a 2 with one roll of the dice?
1 out of 6 times,or 16.67% probability.
What is the probability of getting a multiple3 when you roll a dice?
It is 2/6 = 1/3
What is the probability of not getting a consecutive 2 when the dice is roll 5 times?
It is 0.9034, approx.
If 11 is the sum and you roll two dice what is the probability of getting 11 if you toss the dice 54 times?
The probability of getting 11 with one throw of 2 dice is 1/6*1/6*2 = 1/18 So the probability of not getting 11 with 1 throw of the dice is 17/18. Tossing the dice 54 times, the probability of not getting 11 54 times is (17/18)54 = 0.0456... So the probability of at least 1 roll of 11 is 1 - 0.0456 = 0.954
What is the probability of getting a sum greater than 5 if you roll 2 dice?
The probability is 26/36 = 13/18.
If you roll two dice what is the probability of getting an odd number?
The probability of getting an odd number when you roll one die is 1 in 2. In order to get an odd sum with two dice, one of them has to be odd and one of them has to be even. The probability of rolling an odd sum is still 1 in 2, since each die is unrelated in probability to the other.
Suppose you roll 2 dice. what is the probability that you will roll a 3 or 5?
The probability that you roll a 3 or a 5 on one or both dice is 20/36 = 5/9
What is the probability if you roll 1 unfair dice 2 times of getting two fives where the probability of 5 is 0.3?
0.3 * 0.3 = 0.09
What is the probability of rolling the sum of two if you roll a pair of dice sixty times?
The probability of getting a sum of 2 at least once is 0.8155
When you roll two dice what is the probability their sum is 2?
For a single roll of a pair of fair dice, the answer is 1/36.
What is the probability of getting a 2 or 12 on two dice?
The probability of getting a 2 or 12 on two dice is 2 in 36, or 1 in 18.
