Gianna has a bag that contains pineapple chews, cherry chews and lime chews. She performs an experiment. Gianna randomly removes a chew from the bag, records the result, and returns the chew to the bag Gianna performs the experiment 49 times. The results are shown below: A pineapple chew was selected 25 times. A cherry chew was selected 21 times. A lime chew was selected 3 times. Based on these results express the probability that the next chew Gianna removes from the bag will be cherry chew as a percent to the nearest whole number.

To find the probability that the next chew Gianna removes from the bag will be a cherry chew, we need to use the experimental probability based on the results of her experiment.The experimental probability of selecting a cherry chew is calculated as follows:
Given:- Number of times a cherry chew was selected = 21- Total number of trials = 49So,
To express this probability as a percent, we multiply by 100:
Now, let's calculate this:
Rounding to the nearest whole number, the probability that the next chew Gianna removes from the bag will be a cherry chew is approximately 43%.So, the final answer is:
