With a standard 6 faced die, numbered 1 through 6, there are three odd numbers, 1, 3, and 5, of which 3 and 5 are prime, and there is one even prime, 2. The probability, then, of rolling an odd number which is prime is 1 in 3, i.e. 3 or 5 out of a possible result set of 1, 2, 3, 4, 5, and 6.
Even probability: 3/6= 1/2 Odd probability: 3/6= 1/2 (a cube has six sides and normally is numbered 1-6)
Odd prime numbers from 1-6 are 2, 3, and 5. Since there are three numbers, it would be three out of six, or 3/6 which can be simplified to 1/2 aka 50%.

If I understand the question correctly, you want the probability of each cube showing an odd number. If the number cubes are fair, then the answer is 1/4.
3 is the smallest odd prime number.
The probability of rolling an odd number on a standard die is 3 in 6, or 1 in 2, or 0.5.
The probability of rolling an odd number is 3/6 (or rather, 1/2), so the probability of rolling an odd number three times in a row is 1/2^3 is 1/8 or 12.5%.
The probability that, when rolling three dice none will come up odd is broken down by the probability that on odd roll will occur as an independent event. Rolling the first die has a probability of 3/6 that it will be odd. Rolling the second has the probability of 3/6 that it will be odd. Rolling the third has a probability of 3/6 will be odd. Rolling three and coming up with odd is really the probability that no odd numbers occurred, so therefore an even number DID happen (3/6), and an even number DID happen (3/6), and an even number DID happen (3/6). That's really just 1 - (3/6^3) or simplified 1 - (1/2^3). So therefore the probability that an odd number occurred in 3 die rolls is about 87.5%.
In probability questions, the word "or" means add. Assuming the numbers are 1-12, the prime numbers would be 1, 2, 3, 7, and 11. The odd numbers are 1, 3 , 5, 7, 9, and 11. You don't add duplicates when determining probability, so all your options for a prime number or an odd number are 1,2,3, 5, 7, 9, and 11. This means there are 7/12 that are prime or odd, or a probability of 0.5833.
The probability of rolling an odd number of a standard die is 3 in 6, or 1 in 2, or 0.5.
The probability for a normal die is 1/2.
There could be many questions: What is the probability of rolling an even number. What is the probability of rolling an odd number. What is the probability of rolling a number less than 4. What is the probability of rolling a number more than 3. What is the probability of rolling 1,4, or 6. Basically it could be any question about the probability of rolling half of the faces.
Odd- 3/12 ---> 1/4 Prime- 3/12 ---> 1/4 They are the same
The probability of rolling a 4 is 1/6. (There are 6 numbers one of which is "4")The probability of rolling an odd number is 3/6 = 1/2 (There are 6 numbers 3 of which are odd)Thus, in one roll of the die, the odds of rolling a 4 oran odd number = 1/6 + 3/6 = 4/6 = 2/3.
The probability of rolling a odd number on a standard die is 3 in 6, or 1 in 2, or 0.5.You don't say with what, so I assume with a standard six sided die. The probability of rolling an odd number with a standard six sided die is 3 in 6, or 1 in 2, or 0.5.
The probability of rolling a odd number on a standard die is 3 in 6, or 1 in 2, or 0.5.You don't say with what, so I assume with a standard six sided die. The probability of rolling an odd number with a standard six sided die is 3 in 6, or 1 in 2, or 0.5.
The probability of a head is 1/2. The probability of an odd number is 1/2. 1/2 x 1/2 = 1/4 or 0.25
