Answer:
0.88 = 88% probability that the next apples he picks will be good
Explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In an experimental probability, we have the number of outcomes a priori, that is, before the trial.
What is the experimental probability that the next apples he picks will be good?
250 apples, 250 - 30 = 220 good.
0.88 = 88% probability that the next apples he picks will be good
