What are first 15 prime numbers By dividing by 2 and by 3?

When the spinner is spun once what is the prbability of spinning a prime number?
To determine the probability of spinning a prime number on a spinner, we first need to identify the prime numbers on the spinner. Prime numbers are integers greater than 1 that are only divisible by 1 and themselves. Common prime numbers less than 10 include 2, 3, 5, and 7. If the spinner has numbers 1 through 10, there are 4 prime numbers out of 10 possible outcomes. Therefore, the probability of spinning a prime number on the spinner is 4/10 or 40%.
