The probability is 3 out of 10.
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.
no. because there are more composite numbers than prime numbers It depends on the place you choose to pick the prime number (e.g. 457 or 7577?). The bigger the number the less likely it is a prime.A formula gives the probability for a number being prime (Prime Number Theorem).
"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.
It is 0.4
The three prime numbers on the cube are: 2 3 and 5 so the probability is 3/6 or 1/2 simplified

If the numbers are 1 to 6, there are three prime numbers in that range, a probability of 50%.
15 from 49
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
"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 is 8/20.
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..
It is 0.4
15/49ExplanationThere are 15 prime numbers between 1 and 49 (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47). If you randomly choose one natural number from the 49 numbers between 1 and 49 inclusive, there is a 15/49 probability that it will be prime.
If he's rolling a conventional 6-sided number cube (and it's fair), that's 5 out of 6.
In probability questions, the word "or" means add. Assuming the numbers are 1-12, the prime numbers would be 1, 2, 3, 7, and 11. The odd numbers are 1, 3 , 5, 7, 9, and 11. You don't add duplicates when determining probability, so all your options for a prime number or an odd number are 1,2,3, 5, 7, 9, and 11. This means there are 7/12 that are prime or odd, or a probability of 0.5833.
