There are 6 numbers on the die; 3 even. Therefore P(Even) = 3/6 or 1/2.

there are 6 numbers on a die 3 are even, therefore, p=3/9 or 1/2

What is the probability of rolling an even number with 3 dice?
With one roll of three dice, the probability is 7/8.
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.
If you roll a number Cube twice what is the probability of rolling a even number than an odd number?
50 percent
If you roll a fair six sided number cube. What is the probability of rolling and eight?
The probability is 0.
What is the probability of rolling a 3 or a 4?
2/6 or 1/3 or 0.3333.
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.
Find the probability of rolling a 2 on a number cube and then an even number on two consecutive rolls of a number cube?
1/6,3/6 ----------------------------------------------------------------------------------------------------- The probability of rolling a 2 is: P(2) = 1/6 The probability of rolling an even number is: P(even) = 1/2 The result on the second roll is independent of the result in the first roll. The probability of rolling a 2 and then rolling an even number is: P(2,even no.) = (1/6) ∙ (1/2) = 1/12 = 0.08333... ≈ 8.33%
What is the probability of rolling an even number with 3 dice?
With one roll of three dice, the probability is 7/8.
You roll a dice once what is the probability that you roll an even number?
The same as rolling an odd number... 1:2 or 50% chance.
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.
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 five with a pair of dice?
There are 36 possible outcomes when we roll a pair of dice. Rolling a five can be done the following ways: 3-2, 4-1, 2-3 and 1-4. That's four ways to roll a five with one roll of the dice. The odds of rolling a five are 4 in 36, or 1 in 9. That makes the probability of rolling a five equal to 0.11111....We know that the probability of something is a ratio of the number of times it can be done to the total number of things that are possible. Probabilities range from zero to one, inclusive. If something has a probability of zero, it cannot happen. Like rolling a 13. A 13 cannot be rolled with one roll of a pair of standard dice. Thus the probability of rolling a 13 is zero, as it cannot happen.If something has a probability of one, it must happen. Like the probability of rolling an odd or an even number with one roll of a pair of dice. Since any number we roll must be either odd or even, then the probability of rolling an odd or an even number with one roll of a pair of dice is one. An odd or an even number must turn up, and that is why the probability of rolling an odd or an even number with one roll of the dice is one. Lastly, we've seen that the probability of rolling a given number with one roll of the dice is the number of times that number might appear divided by the total number of possibilities that might appear.
What is the probability of rolling an even prime number with one roll of a die?
Since there is only one even prime, 2, the probability of rolling a 2 with one die is 1 in 6.
Suppose you roll one die find the probability of not rolling an even number?
Not even is odd. Odd is 1,3,& 5 which is 1/2 of the numbers on the die. Therefore the probability of not rolling an even number is 1/2 or 0.5.
Suppose you roll one die what is the probability of rolling an even number?
As there are an equal number of odd and even numbers on a single die, the odds of rolling an even number would be 50/50.
What is the probability of rolling an even number on a die and rolling an odd number on a second roll of the same die?
0.25 ( P = 0.5 each time)
What is the probability of rolling an even prime number with one roll a number cube write the probability as a fraction and as a decimal number to the nearest hundred?
1 in 6, or 0.17.
