If you mean rolling at least one three, the 1/3.
If you mean exactly one three, then 5/18.
and
If you mean a sum of 3 for the two throws, the answer is 1/18

If a number cube is rolled 4 times what is the probability that the same number is rolled at least twice?
It is 0.722... recurring.
When rolling a number cube twice what is the probability of rolling at least one even number?
one fourth
When a dice is rolled what is the probability of rolling a 3 twice?
Rolling it once there is a 1 out of 6 chance - because there is 6 numbers on a dice and one of them is three. so rolling it twice would be a 2 out of 12 chance / 0.16 / 16% chance
If You roll a fair number cube twice What is the probability of rolling two threes if the first roll is a 5?
2/36 what you rolled the first time has nothing to do with the next roll. It's an independent event.
What is the probability of having the same number when rolling a dice twice?
If it is a regular dice then the probability is 3/6 that is 1/2
The probability of rolling an even number when number cube is rolled twice?
Because 3/6 of the sides on a number cube have even numbers, the probability of rolling even on one number cube is 1/2(equivalent of 3/6). But since you're rolling twice, you multiply the probability of one by itself (therefore rolling 2 number cubes). So: 1/2x1/2=1/4 The probability of rolling an even number when a number cube is rolled twice is 1/4, 25%, or 1 out of 4.
A number cube is rolled 2 times in a row What is the probability of rolling a 3 both times?
When a number cube is rolled twice, there are 36 possible outcomes. (1,1),(1,2),....(6,6). (3,3) occurs only once. Therefore, the probability of rolling a 3 both times is 1/36.

If you roll a number Cube twice what is the probability of rolling a even number than an odd number?
50 percent
What is the probability of rolling a sum of 7 when rolling one die twice?
The probability is 1/6.
What is the probability of rolling a 3 twice whit two rolls of a number cube?
It is 1/36.
What is the probability of rolling a dice twice?
That depends on whether you roll it twice or not...
What is the probability of rolling a 7 twice in two rolls of a pair of dice?
The probability of rolling 7 once with two dice is 1 in 6, o 0.1667. The probability, then, of doing that twice in a row is 1 in 36, or 0.02778.
