From 10 to 30, there are 21 numbers.
Six of them are prime numbers: 11, 13, 17, 19, 23, and 29.
If you pick a number at random from 10 to 30, the probability
that it's a Prime number is
6/21 = 2/7 = 28.57% (rounded)

What is the probability of getting at least one prime number in two dice?
The probability of getting at least one prime number in two dice is 3/4.
If you roll a die what is the probability of rolling a prime number?
"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.
What is the probability of getting a prime number on throwing a dice?
1 out of 2.
What is the probability that you get a prime number with one dice and a tail on a coin?
The prime numbers from 1-6 are 2, 3, 5 (1 is not prime). There are 3 prime numbers on a dice and 6 total. therefore the probability of rolling a prime is 3/6. The probability of getting a tails when flipping a coin is 1/2. Therefore you just multiply the two. 3/6 * 1/2 = 1/4
Is the probability of picking a prime number greater than picking a number that is not prime?
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).
