The answer will depend on

- what a 8 sliced (?) dice are
- how many such dice there are
- what numbering scheme is used on each 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.

tHere is a 24 percent chance of rolling a prime number because 1,2,3, and five are all prime numbers. 4 out of 6 is the same as 24 perceNt.

With a standard 6-sided die, the probability of rolling a prime number is 1/2

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.
