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.
The probability of selecting an orange chew or an apple chew is the sum of the probabilities of selecting each one individually.
P(orange or apple) = P(orange) + P(apple)
P(orange) = 25/51
P(apple) = 16/51
P(orange or apple) = 25/51 + 16/51 = 41/51
Rounded to the nearest hundredth, the probability that the next chew Aubree removes from the bag will be orange or apple is 0.80.
