Question

Aaden has a bag that contains strawberry chews, apple chews, and watermelon chews. He performs an experiment. Aaden randomly removes a chew from the bag, records the result, and returns the chew to the bag. Aaden performs the experiment 31 times. The results are shown below:
A strawberry chew was selected 4 times.
A apple chew was selected 7 times.
A watermelon chew was selected 20 times.

Based on these results, express the probability that the next chew Aaden removes from the bag will be a flavor other than apple as a fraction in simplest form.

Answer 1

There were 31 trials and 7 apples, so non-apple outcomes = 31 − 7 = 24. The experimental probability the next chew is not apple is 24/31.
