When rolling 1 dice what is the probability of rolling number 4?
It is 1 (a certainty) if you roll it often enough. For a single roll of a fair die, the probability is 1/6.
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 a number greater than 3 on roll of a die?
One out of two
What are the probability of rolling a prime number on one roll of a die?
1 out of 2 if the die is six-sided.
What is probability of rolling a number less than 6 on 1 roll of a die?
With a fair die it is 5/6.

What is the probability of rolling a prime number on one roll of a die?
3/6
What is the probability of rolling a number that is greater than 3 on a roll of a die?
It is 0.5
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)
If roll a twelve sided die what is the probability of rolling a prime number?
5 out of 12
What is the probability of rolling a number greater than 3 on one roll if a die?
It is 0.5
What is the probability of rolling a number greater than 3 on roll of a die?
One out of two
What are the probability of rolling a prime number on one roll of a die?
1 out of 2 if the die is six-sided.
The probability of rolling a number less than 6 on one roll of a die?
1 out of 2
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.
What is probability of rolling a number less than 6 on 1 roll of a die?
With a fair die it is 5/6.
How do you find the probability of rolling a number less than a certain number on one roll of a die?
The probability of rolling a number on a die is 1 out of the number of sides on the die. So, for a six sided die, the probability of rolling a 4 is 1/6. The probability of rolling a 4 or a 5 becomes 2/6 or 1/3. This is because there are two acceptable outcomes out of six. So when finding the probability of rolling a number less than x on a y sided die, it becomes x-1 / y. It is x-1 because the outcome is to roll less than the number, not less than or equal.
