Predicting whether it will rain or not tomorrow evening at a particular time is a type of _________ problem.

Predicting whether it will rain or not tomorrow evening is a type of classification problem in the field of machine learning and statistics. In this context, classification problems involve categorizing input data into predefined classes or categories based on certain features or conditions.

In this case, the task involves analyzing various meteorological data points (like temperature, humidity, wind speed, etc.) to classify the outcome into two categories: "rain" or "no rain." This type of problem is commonly solved using various statistical methods, decision trees, or machine learning algorithms, which can process and learn from historical weather data to make predictions about future weather conditions.
