Let say the dice has n sides
Let first search for the probability to roll a number less or equal to 2
Probability to roll a 1 = 1/n
Probability to roll a 2 = 1/n
Probability to roll a 1 OR a 2 = Probability to roll a 1 + Probability to roll a 2
= 1/n + 1/n = 2/n
Probability to roll a number greater than 2 = 1 - (Probability to roll a 1 OR a 2)
= 1 - 2/n = (n-2)/n
If n = 6 then the result is (6-2)/6 = 4/6 = 2/3

1/36
If you Roll a 4 or higher on a six-sided number cube what is the probablity?
The probability of rolling a 4 or higher on a standard die is 1 in 2.
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 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 is the probaability of rolling a number greater than 4 on one roll of die?
three sixths
What is the probability of rolling a number greater than three if you roll a die two times?
fifty percent
What is the probability of rolling a number greater than 2 on one roll of a die?
4 over/out of 6
The probability of rolling a number greater than 5 on one roll of a die?
Only 6 is greater than 5 on a standard cubic die. The chance of rolling a 6 is one in six.
What is the probability of rolling a number greater than 3 on a roll of die?
Sample space, roll of 1 die, is: 1, 2, 3, 4, 5, 6. The numbers greater than 3 are: 4, 5, 6; which is 1/2 of the sample space. So, probability of rolling a number greater than 3 on one roll of a die is 1/2 or 0.5.
What is the probability of rolling a number greater than 3 on one roll of a die?
Sample space, roll of 1 die, is: 1, 2, 3, 4, 5, 6. The numbers greater than 3 are: 4, 5, 6; which is 1/2 of the sample space. So, probability of rolling a number greater than 3 on one roll of a die is 1/2 or 0.5.
What is the probability of rolling a number less than 3 and greater than 4 with one roll of a number cube?
The probability is zero. No number can be less than 3 and greater than 4.
