What Is the Probability of Drawing a Prime Number Between 1 and 30?

Learn how to calculate the probability of selecting a prime number from 1 to 30, including the list of primes and the final probability.

0 views

The probability of drawing a prime number between 1 and 30 is calculated by identifying prime numbers in this range first. There are 10 prime numbers (2, 3, 5, 7, 11, 13, 17, 19, 23, 29) out of 30 total numbers. Therefore, the probability is 10/30 or 1/3, making the chance of drawing a prime number 33.33%.

FAQs & Answers

  1. What are prime numbers? Prime numbers are natural numbers greater than 1 that have no divisors other than 1 and themselves.
  2. How do you calculate the probability of an event? Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
  3. Which numbers between 1 and 30 are prime? The prime numbers between 1 and 30 are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29.
  4. What is the probability of drawing a prime number between 1 and 30? There are 10 prime numbers between 1 and 30, so the probability of drawing one is 10 out of 30, or 1/3 (approximately 33.33%).
