Since In total there is 25 attractions and shops , you would add them because there is still a chance that if it was randomly selected you would get a attraction. If 5/20 is the probability, you would divide 5 by 20 because the “ / “ sign means divide. And if it said 5 of 20 , it would mean multiply as “of” means multiply. So after you do the 5 divided by 20 , it equals 0.25, which comes out to a quarter of 100 which means it is 1/4 chance of getting a gift shop chosen. Answer : 1/4.
