Which of the following best describes an unpredictable event?​
Anna35 [415]

Answer:

B. The weather on a particular day a year from now

Step-by-step explanation:

We can only predict the weather in the near future, not long term or all time. The rest of the answer choices are predictable. We will always know the age of a person 10 years from now, we can predict the rating of the movie if we preview and watch it, and if a student studies enough/not enough we can predict the type of grade they will get on a test.
