There are a number of asymptotic distributions developed by various mathematicians. A simple one to sues is that, given an integer N, the probability that a random positive integer which is not greater than N is prime is very close to 1 / ln(N) where ln(N) is the natural logarithm of N..

That depends how large the numbers are that you choose from. If you choose a random number close to "n", the probability that "n" is a Prime number is approximately 1 / ln(n).

"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.
