Cameron has a bag that contains strawberry chews, apple chews, and watermelon chews. He performs an experiment. Cameron randomly removes a chew from the bag, records the result, and returns the chew to the bag. Cameron performs the experiment 40 times. The results are shown below:

Question

A strawberry chew was selected 21 times.
A apple chew was selected 7 times.
A watermelon chew was selected 12 times.

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

Answer 1

The probability that the next chew Cameron removes from the bag will be a flavor other than watermelon is calculated by adding the probabilities of selecting a strawberry or apple chew:

Probability = (Number of strawberry chews + Number of apple chews) / Total number of chews
Probability = (21 + 7) / 40
Probability = 28 / 40
Probability = 7 / 10

Therefore, the probability that the next chew Cameron removes from the bag will be a flavor other than watermelon is 7/10.
