Probability theory: What are the classical, relative, and subjective meanings?
Understand the Problem
The question is asking for the definitions and distinctions between classical, relative, and subjective interpretations of probability theory. This involves explaining the different approaches and frameworks used to understand probability in various contexts.
Answer
Classical probability is based on equally likely outcomes due to symmetrical reasoning. Relative (empirical) probability derives from historical data or experiments. Subjective probability reflects personal beliefs or judgments.
Classical probability involves outcomes that are considered equally likely due to inherent symmetry or reasoning, such as rolling a fair die. Relative or empirical probability is determined by observing frequencies over numerous trials, often based on historical data, like finding the probability of rain based on past weather patterns. Subjective probability, on the other hand, is based on personal belief or intuition, without the necessity for prior data or mathematical calculation, like estimating the likelihood of a team winning a game based on one's perception of their skill.

More Information
Each type of probability provides a different approach for estimating how likely an event is to occur, catering to varied contexts like theoretical analysis, data-based observation, or personal estimation.
Tips
A common mistake is confusing subjective probability with empirical probability; remember that subjective probability is based on personal judgment, not past data.
