Question

Aubree has a bag that contains orange chews, apple chews, and watermelon chews. She performs an experiment. Aubree randomly removes a chew from the bag, records the result, and returns the chew to the bag. Aubree performs the experiment 51 times. The results are shown below:

A orange chew was selected 25 times.
A apple chew was selected 16 times.
A watermelon chew was selected 10 times.

Based on these results, express the probability that the next chew Aubree removes from the bag will be orange or apple as a decimal to the nearest hundredth.

Answer 1

The total number of times Aubree performed the experiment is 51. The number of times an orange or apple chew was selected is 25 + 16 = 41. Therefore, the probability of selecting an orange or apple chew is 41/51. To express this as a decimal to the nearest hundredth, we divide 41 by 51 and get 0.80. Therefore, the probability of selecting an orange or apple chew is 0.80 (or 80%).
