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 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.
What is the probability of rolling the sum of 12 with 2 dice?
Since you need a specific number - the number 6 - twice, the probability is (1/6)2, which is equal to 1/36.Since you need a specific number - the number 6 - twice, the probability is (1/6)2, which is equal to 1/36.Since you need a specific number - the number 6 - twice, the probability is (1/6)2, which is equal to 1/36.Since you need a specific number - the number 6 - twice, the probability is (1/6)2, which is equal to 1/36.
What is the probability of rolling a 4 twice with two rolls of a number cube?
Let A be the event of rolling a 4. P(A) = 1/6 P(A)P(A)=(1/6)(1/6)=1/36 Therefore, the probability of rolling a 4 twice with two rolls of a number cube is 1/36.

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
What is the probability of rolling a 3 when a number cube is rolled twice?
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 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.
