How can probability be applied to predict weather outcomes?
Weather outcomes can only be predicted by using computer simulations without data analysis.
Probability can be applied to predict weather outcomes by analyzing historical data and using statistical models to assess the likelihood of various weather events.
Probability is irrelevant in weather forecasting.
Weather predictions are solely based on intuition.
