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.

The answer depends on the sum of WHAT!
no.
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.
This cannot be answered Until and Unless a certain set of numbers are given as Sample Space.

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.
Well, honey, there are 15 prime numbers between 1 and 50. So, the probability of choosing a prime number from that range would be 15 (prime numbers) divided by 50 (total numbers), which simplifies to 3/10 or 30%. Math doesn't have to be boring, darling!
