Assuming that the faces of the 20 sided die are numbered 1 to 20, then the probability of rolling a number less than 9 is 8 in 20, or 0.4.

What is the probability of rolling a number less than 8 on a fair six sided dice?
The probability is 1.
What is the probability of rolling a number less than 4 on a 6 sided die?
1 out of 2
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.
What is the probability of rolling a number less than 3 on a 6-sided number cube numbered from 1 to 6?
2/6 which equals 1/3
What is the probability of rolling a number less than five on a standard number cube?

What is the probability of rolling a number less than 5 with a six-sided die?
2/3
What is the probability of rolling a number less than 4 on a 6 sided die?
1 out of 2
How do you find the probability of rolling a number less than a certain number on one roll of a die?

3 out of 6, or 50%
What is the probability of rolling a number less than 3 on a 6-sided number cube numbered from 1 to 6?
2/6 which equals 1/3
What is the question of the problem if rolling a number cube labeled from 1 to 6 and the probability is one half?
There could be many questions: What is the probability of rolling an even number. What is the probability of rolling an odd number. What is the probability of rolling a number less than 4. What is the probability of rolling a number more than 3. What is the probability of rolling 1,4, or 6. Basically it could be any question about the probability of rolling half of the faces.
When rolling a number cube what is the probability of rolling a number less than 3?
It is: 1 in 3
What is the probability of rolling a number less than five on a standard number cube?
There is a 4 in 6 (or 2 in 3) probability of rolling a number less than a five on a standard number cube.
An ordinary six-sided dice is thrown what is the probability that the score is less than 3?
There are six possible outcomes of rolling a six sided die.However, only two of these (1 and 2) are favorable.So, the probability of rolling less than three is 2/6 = 1/3.
