The difference between classical and empirical probability is that classical probability assumes that certain outcomes are equally likely (such as the outcomes when a die is rolled), while empirical probability relies on actual experience to determine the likelihood of outcomes. Which form do you think we use mostly when it comes to business? Or in

Differentiate between classical, empirical, and subjective probability. Provide examples for each type. The Correct Answer and Explanation is : Classical Probability:Classical probability, also known as theoretical probability, refers to situations where all outcomes are equally likely. It is based on the assumption that every outcome in a given sample space has an equal chance of
