The odds of choosing a Prime number in the set [1-20] are 8 out of 20, as there are 8 prime numbers, 2, 3, 5, 7, 11, 13, 17, and 19, in that set.

Choose an odd number. it will most likely be relativity prime to another number.
To choose a number that is relatively prime to any other number, you need to select a number that has no common factors (other than 1) with those other numbers. One way to ensure this is to choose a prime number. Prime numbers only have two factors: 1 and itself, making them relatively prime to any other number.
In this problem, the total number of possibilities is 20, so n = 20.The set of prime numbers from 1 to 20 = {2, 3, 5, 7, 11, 13, 17, 19}, so f = 8Probability = f/n = 8/20 = 0.4.You have a 2 in 5 chance of choosing a prime number from 1 to 20.
13 is a prime number between 1 and 100. There are 24 others.

The prime numbers from one to nine are 2, 3, 5, and 7. There are nine numbers from one to nine. The probability is 4 (the number of prime numbers) over 9 (the total number of numbers). Therefore, the probability of choosing a prime number is 4/9 or about 44 percent.

Choose an odd number. It has better chances to be a prime.And all prime numbers except 2 are odd.Simple fact..
There isn't a prime number between 63 and 65
