What is the probability of getting a composite number in the list of natural numbers from 1 to 50?

  1. A. \frac{7}{10}
  2. B. \frac{17}{25}
  3. C. \frac{18}{25}
  4. D. \frac{33}{50}

Correct Answer: B. \frac{17}{25}

Explanation

There are 15 prime numbers between 1 and 50. The number 1 is neither prime nor composite. The number of composite numbers is 50 - 15 - 1 = 34. The probability is \frac{34}{50} = \frac{17}{25}.
