Question

What is the probability of choosing a prime number from 1 to 10​

Answer 1

Answer:

2/5 or 40%

Step-by-step explanation:

The probability that a prime is selected from 1 to 10 requires us to divide the number of primes from 1 to 10 by 10.

The numbers 2, 3, 5, 7 are prime, so the probability that a prime is selected is 4/10 = 40%

Answer 2

Answer:

We divide the number of primes less than or equal to x by the number x. For example, to find the probability that a prime is selected from 1 to 10 requires us to divide the number of primes from 1 to 10 by 10. The numbers 2, 3, 5, 7 are prime, so the probability that a prime is selected is 4/10 = 40%
