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).
16 in 52 chance.
The probabiliy of selecting odd or prime numbers from 1 to 50. First find out the probability of selecting odd numbers : 25/50 is 1/2. Lets find out the probability of selecting prime numbers: 15 / 50 . so, total is 40/ 50 is 0.82.

There are eight prime numbers between 1 and 20.2, 3, 5, 7, 11, 13, 17, 19If you randomly choose in number then you have an 8 in 20 chance of selecting a prime.The probability is selecting a prime number is 8/20 or 0.4
It is 0.4
16 in 52 chance.

The answer depends on what you are selecting from. If you are selecting months in which the equinoces occur, the probability is 0.5
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.
