Ryan has a bag that contains strawberry chews, cherry chews, and watermelon chews. He performs an experiment. Ryan randomly removes a chew from the bag, records the result, and returns the chew to the bag. Ryan performs the experiment 55 times. The results are shown below: A strawberry chew was selected 15 times. A cherry chew was selected 20 times. A watermelon chew was selected 20 times. Based on these results, express the probability that the next chew Ryan removes from the bag will be cherry or watermelon as a fraction in simplest form.
