Question

If an integer from 1 through 20 is chosen at random, what is the probability that the number chosen is prime?

Answer 1

40%

Explanation:

8 (number of prime numbers through 1-20) / 20 (total numbers from 1 to 20) = 0.4 or 40%.

This means that the probability of the number being chosen as a prime number is 40 percent or 0.4. Hope this helps!
