Question

Salma has a bag that contains orange chews, cherry chews, and lime chews. She performs an experiment. Salma randomly removes a chew from the bag, records the result, and returns the chew to the bag. Salma performs the experiment 28 times. The results are shown below:
A orange chew was selected 20 times.
A cherry chew was selected 5 times.
A lime chew was selected 3 times.

Based on these results, express the probability that the next chew Salma removes from the bag will be orange or cherry as a fraction in simplest form.

Answer 1

There were 25 favorable outcomes (20 orange + 5 cherry) out of 28 trials, so the estimated probability is 25/28.
