Verified answer
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.

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.
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.
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 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.
Probability of rolling a 3 twice with 2 rolls on a cube?
Probability of a 3 on the first roll = 1/6Probability of a 3 on the second roll = 1/6Probability of both of them = (1/6) x (1/6) = 1/36 = 0.0277777 = 2.78% (rounded)
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 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 are the odds of rolling doubles with one die in 25 rolls?
I'm going to assume you mean rolling the same number twice in a row in 25 rolls. The first won't cause a double, so you just need to consider the odds of rolling the same number as the last for the last 24 rolls. The easier approach is to realize that the probability of rolling at least one double is 1 minus the probability of rolling no doubles. One roll has this probability of not rolling the same as the last: P(different number from last) = 5/6 Since they are independent events: P(no doubles in 25 rolls) = (5/6)24 Now the final probability, of at least one double, is 1 - (5/6)24
When rolling a number cube twice what is the probability of rolling at least one even number?
one fourth
What is the probability of rolling the same number twice?
In 2 rolls, it's 1/6 = 162/3% if you don't care what the number is.If you name the number you want before rolling, it's 1/36 = 27/9%.
The probability of rolling an even number when number cube is rolled twice?

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.
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 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 rolling a sum of 7 when rolling one die twice?
The probability is 1/6.
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
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 dice twice?
That depends on whether you roll it twice or not...
