The question depends on what the numbers are being rolled on: a hexahedron or some other shape.

Out of the six faces, only 3 and 5 match the requirements, so the probability is 2/6 or 1/3.

If the die is rolled often enough, the probability is 1. With only two rolls of a fair die, the probability is 1/6.

When a fair die is thrown the probability that a prime number will occur is 2:1

"The probability of getting a prime number in a die is 4/6" Actually there are 3 prime numbers on a die. 2, 3, and 5 are all prime numbers. So this tells you that you have 3 chances it will be a prime number and 3 chances it will not be a prime number. So the probability of getting a prime number on a die would be 3/6 or 1/2.

The probability of getting at least one prime number in two dice is 3/4.

The probability of eventually throwing a prime number is 1. On a single throw, of a fair die, the probability is 1/2.

The probability is 3 out of 10.

no. because there are more composite numbers than prime numbers It depends on the place you choose to pick the prime number (e.g. 457 or 7577?). The bigger the number the less likely it is a prime.A formula gives the probability for a number being prime (Prime Number Theorem).

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.
