"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 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.
With a standard 6-sided die, the probability of rolling a prime number is 1/2
Since there is only one even prime, 2, the probability of rolling a 2 with one die is 1 in 6.
1 out of 2
When a fair die is thrown the probability that a prime number will occur is 2:1

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 it many times. The probability that it lands on a six is the number of times that it lands on a six divided by the number of times the die has been rolled.
With a standard 6-sided die, the probability of rolling a prime number is 1/2
If the die is rolled often enough, the probability is 1. With only two rolls of a fair die, the probability is 1/6.
Since there is only one even prime, 2, the probability of rolling a 2 with one die is 1 in 6.
2:3
