What attributes does a probablity have?

Probability has several key attributes: it ranges from 0 to 1, where 0 indicates impossibility and 1 indicates certainty. It is a measure of the likelihood of an event occurring, often expressed as a fraction, decimal, or percentage. Additionally, the probabilities of all possible outcomes in a sample space must sum to 1. Lastly, probability can be classified into different types, such as theoretical, experimental, and subjective probability.
