"The probability of getting a Prime number in a die is 4/6"
Actually there are 3 prime numbers on a die. 2, 3, and 5 are all prime numbers. So this tells you that you have 3 chances it will be a prime number and 3 chances it will not be a prime number. So the probability of getting a prime number on a die would be 3/6 or 1/2.

What is the probability of rolling a prime number with one roll of a number cube?
1/6
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 the probability of rolling a prime number?
total numbers taht can be occure=1,2,3,4,5,6 prime number taht can occure in a roll= 2, 3,5 total sample space= n=6 total faverable cases= m=3 P(prime number)=m/n=3/6=1/2 probability of rolling a prime number is 1/2
When rolling a six on the first roll of a 1 6 number cube and rolling an odd number on the second roll of the same cube?
and the question is ... ?
What is the probability of getting a prime number when you roll a dice?
On a standard die, 2:1 in favour. This would be correct if 1 and 2 are accepted as prime numbers, which is allowed by some mathematicians and theories though not by all. ---- Having worked it out myself, I believe there is actually an even probability: Prime numbers: * 2 * 3 * 5 Not-prime numbers: * 1 * 4 * 6
What is the probability of rolling a prime number with one roll of a number cube?
1/6
What is the probability of rolling a prime number on one roll of a die?
3/6
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 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 the probability of rolling a prime number on a six sided dice?
The probability is 1 out of two. The primes you can roll are 2,3, and 5.
Odds Rolling prime number sum with roll of two dice?
The probability is 5/12.
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 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.
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.
What is the probability of rolling a prime number and the probability of rolling a number greater than 1 on two rolls fo a die?
First you need to work out the probability of rolling a prime number. The prime numbers on a die are 2, 3 and 5. Thus the probability of rolling a prime number is 3/6 which can be simplified to 1/2. The probability of rolling a number greater than 1 is 5/6. The probability of rolling one on one dice and one on the other is therefore 1/2 x 5/6 = 5/12. There are two possible ways round these options could come though. You might get the number greater than one on the first roll, and the prime on the second. Thus we need to multiply the probability by 2, which gives us the final answer of 5/6.
What is the probability of rolling a prime number if you roll to dice at the same time?
Assuming that "to" should actually be "two", Since the outcome on each die is independent, Pr(Roll a prime when rolling two dice) = Pr(Roll a prime on a die)2 = (1/2)2 = 1/4
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.
