Carlos has a bag that contains pineapple chews, lemon chews, and watermelon chews. He performs an experiment. Carlos randomly removes a chew from the bag, records the result, and returns the chew to the bag. Carlos performs the experiment 73 times. The results are shown below: A pineapple chew was selected 34 times. A lemon chew was selected 19 times. A watermelon chew was selected 20 times.
