Explanation:
dice 1 can roll 6 possible numbers
dice 2 can roll 6 possible numbers
possible outcomes: 6x6= 36
prime outcomes = 2, 3, 5, 7, 11
2-->(1,1)-->1
3-->(1,2) and (2,1)-->2
5-->(1,4) (4,1) (2,3) and (3,2) -->4
7-->(1,6) (6,1) (2,5) (5,2) (3,4) and (4,3)-->6
11->(5,6) (6,5)-->2
1+2+4+6+2=15

What is the probability of getting at least one prime number in two dice?
The probability of getting at least one prime number in two dice is 3/4.
What is the probability of getting a prime number on throwing a dice?
1 out of 2.
What is the probability that you get a prime number with one dice and a tail on a coin?
The prime numbers from 1-6 are 2, 3, 5 (1 is not prime). There are 3 prime numbers on a dice and 6 total. therefore the probability of rolling a prime is 3/6. The probability of getting a tails when flipping a coin is 1/2. Therefore you just multiply the two. 3/6 * 1/2 = 1/4
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
If you are going to throw a fair eight sided dice numbered twelve to nineteen what is the probability the you will throw a prime number?
Since there are 3 prime numbers, 13, 17, and 19, in the range 12 to 19, the probability of throwing a prime number on a fair eight sided die numbered 12 to 19 is 3 in 8.
If you roll two standard dice what is the probability that the sum of their spot values will be a prime number?
13/36
You roll 2 dice What is the probability that the sum of the dice is prime and both dice show the number 6?
The probability is 0 since if both dice show the number 6, their sum is 12 which is not a prime.
What is the probability of getting at least one prime number in two dice?
The probability of getting at least one prime number in two dice is 3/4.
What is the probability of getting a prime number on throwing a dice?
1 out of 2.
What is the probability of two prime numbers when rolling two dice?
The probability of rolling two prime numbers on a standard pair of dice is 1 in 4, or 0.25. Take the probability of rolling a prime on one die, 3 in 6, or 1 in 2, or 0.5, and square it.
What are odds of throwing a prime number with a dice?
The probability of eventually throwing a prime number is 1. On a single throw, of a fair die, the probability is 1/2.
You roll 2 dice You can use a Venn diagram to calculate the probability that the sum of the dice is a prime number?
false.
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 a prime number on a role of dice?
50% 1/2 0.5
What if 2 dice are rolled 100 times what is the probability that it will be a prime number?
There are 36 permutations of two standard 6 sided dice. Of those, 15 are prime, namely 2, 3, 3, 5, 5, 5, 5, 7, 7, 7, 7, 7, 7, 11, and 11. The probability of rolling a prime number, then, is 15 in 36, or 5 in 12, or about 0.4167. It does not matter how many times you roll the dice.
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.
What is the probability rolling prime numbers when rolling two dice?
Assuming you mean the sum of the two dice is a prime number, then: The possible outcomes are 2, 3, 5, 7, 11 which occur 1, 2, 4, 7, 2 times respectively. There are 36 possible outcomes → pr(prime_sum) = (1+2+4+7+2)/36 = 16/36 = 4/9 If you mean that both dice must show a prime number, then: The possible primes are 2, 3, 5 → probability of 1 die showing a prime number is 3/6 = ½ → probability both show a prime number is ½ × ½ = ¼ If you mean either or both dice could show a prime number, then: The possible primes are 2, 3, 5 → probability of 1 die showing a primes is 3/6 = ½ → probability of a die not showing a prime is 1 - ½ = ½ → probability of neither die showing a prime is ½ × ½ = ¼ → probability of either or both dice show a prime is 1 - ¼ = ¾
