@bcr1997;  Please!  Our goal here is to help you learn to solve problems on your own, not to supply you with answers.  "Will give medal" sounds like bribery.

If necessary, write out all 24 of the numbers 1 through 24.  Then circle the ones that are not divisible by 3.  for example, 2 and 3 are NOT divisible by 3, but 3 is divisible by 3; 4 and 5 are not, and so on.  Count how many numbers you have circled.  Then divide that count by 24.  That's "the probability of drawing a number not divisible by 3."
