Probability of a 3 on the first roll = 1/6
Probability of a 3 on the second roll = 1/6
Probability of both of them = (1/6) x (1/6) = 1/36 = 0.0277777 = 2.78% (rounded)

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.
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 a 7 with one roll of a standard number cube?
The probability of rolling a seven with one roll of a standard number cube is zero.
When rolling a number cube once what is the probability of rolling a 3?
1 out of 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 6 and then a 1 on consecutive rolls of a standard sided number cube?
If you keep rolling the die, then the probability of rolling a 6 and then a 1 on consecutive rolls is 1.The probability is 1/36 for the first two throws.
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.
What is the probability of not rolling a 6 on a number cube?
The probability of not rolling it ever is 0.For n rolls it is (5/6)n sofor 10 rolls it is 0.1615for 20 rolls it is 2.608*10-2for 100 rolls it is 1.207*10-8 and so on.
When rolling a number cube twice what is the probability of rolling at least one even number?
one fourth
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.
What is the theoretical probability of not rolling a 2 while the cube rolls 50 times?
The theoretical probability of not rolling a 2 while the cube rolls 50 times (calling itevent E) is: P(E) = (5/6)50 = 1.09884819... x 10-4 = 0.000109884810... ≈ 0.011%
When rolling a cube what is the probability 0?
If 0 is not one of the faces on the cube, then then probability of rolling a 0 is 0.
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 an even with one roll of a numbers cube. express the probability as a decimal.?
What is the probability of rolling an even with one roll of a numbers cube.
What is the probability of rolling a 4 on a cube after a 4 has been rolled the last five rolls?
If you are counting each roll separately (if they are independentdent) then 1/6.
Gary rolls a cube numbered from 1 to 6 What is the probability that he will not roll an even number greater than 3?
Gary's chances of rolling either a 4 or a 6 are the same for any of the other numbers on the cube. The probability is 1 out of 3.
