With a standard 6-sided die, the probability of rolling a prime number is 1/2
1 out of 2
The probability of rolling a prime number on a standard 6-sided die is 3 in 6, or 0.5.The sample space is [1 2 3 4 5 6] and the result space is [2 3 5]. 3 divided by 6 is 0.5.
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 mean a regular six-sided die, there are 3: 2,3 and 5. Some people would argue that 1 is a prime number, but in fact 1 is not, as it only has one natural number divisor, while prime numbers have exactly two distinct natural number divisors.
With a standard 6-sided die, the probability of rolling a prime number is 1/2
5 out of 12
1 out of 2
1 out of 2 if the die is six-sided.
It is 1/6
The probability is 6/36 or 1/6
The probability is 1 out of two. The primes you can roll are 2,3, and 5.
The probability of rolling an even number is 1/2.
Odd- 3/12 ---> 1/4 Prime- 3/12 ---> 1/4 They are the same
There are 36 possibilities when rolling two six sided die. 15 of them result in a prime number (2,3,5,7,11) So the probability is 15 in 36 or a 5 in 12 chance.
If he's rolling a conventional 6-sided number cube (and it's fair), that's 5 out of 6.
There is always a 1 in 6 chance of rolling ANY number on a six-sided dice, as there are 6 numbers.
