Question

Gianna has a bag that contains pineapple chews, cherry chews, and lime chews. She

performs an experiment. Gianna randomly removes a chew from the bag, records the
result, and returns the chew to the bag. Gianna performs the experiment 49 times.
The results are shown below:
A pineapple chew was selected 25 times.
A cherry chew was selected 21 times.
A lime chew was selected 3 times.
Based on these results, express the probability that the next chew Gianna removes
from the bag will be cherry chew as a percent to the nearest whole number.

Answer 1

43%

Explanation:

Given an experiment conducted 49 times with the results pineapple, 25; cherry, 21; and lime, 3, you want the probability the next result will be cherry.

Experimental probability

The probability of a given result on the next draw is assumed to match the fraction of times that result occurred on previous draws. The fraction of draws that were cherry was 21/49 ≈ 43%.

The probability the next chew Gianna removes from the bag will be cherry is about 43%.
