What is the probability of rolling an even number or prime number on a number cube?
The probability of rolling an even number on a die is 3 in 6 or 1 in 2. The probability of rolling a prime on a die is 3 in 6 or 1 in 2, but one of those primes is also even. Simply add the probabilities and you find that the probability of rolling an even number or a prime on a die is 5 in 6.
What is the faction of rolling a prime number?
With a standard 6-sided die, the probability of rolling a prime number is 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 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 theoretical probability of rolling a 1 and a prime number on two six-sided number cubes?
The probability is 6/36 or 1/6
What is the probability of rolling a prime number on a 6 face dice?
If the numbers are 1 to 6, there are three prime numbers in that range, a probability of 50%.
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 and flipping a coin and getting tails?
1 in 2.
What is the probability of rolling a prime number on a role of dice?
50% 1/2 0.5
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.
A six sided die is rolled once what is the probability of rolling a prime number?
1 out of 2
What is the probability of getting a six then a prime number?
The probability of rolling a six and then a prime on a die is (1 in 6) times (3 in 6), which is (3 in 12), which is (1 in 4), or 0.25
