Final answer:
Probability is both an objective and subjective term, with applications across numerous fields that inherently deal with uncertainty. Its objective use is seen in frequentist models while subjective interpretations are central to Bayesian perspectives. Dismissing probability as an unneeded term outright neglects its comprehensive role in scientific and decision-making processes.
Step-by-step explanation:
The question asks whether all of probability is subjective and the necessity of the term outright. To address this, we should recognize that probability has both objective and subjective interpretations. The objective interpretation is grounded in the frequency of outcomes in repeated trials, which is used in classical and frequentist probability. In contrast, the subjective interpretation, which involves personal belief about the likelihood of outcomes, is prevalent in Bayesian probability approaches.
While some fields of study advocate for the use of subjective probabilities, in many scientific contexts, especially those relying on probabilistic models, objectivity is sought after. Critical decisions in fields like medicine, engineering, and law require a more objective assessment of probabilities to avoid the pitfalls of individual bias.
To say that probability as a concept is unneeded would ignore its foundational role in various sciences and practical applications. The term 'probability' facilitates understanding and dealing with uncertainty in nearly every domain of inquiry, from simple games of chance to complex quantum mechanics. Context determines the level of certainty required to make decisions, as seen in the differing standards for 'strong' probabilities in gambling versus those in a court of law.
The ideas surrounding human freedom and determinism also touch on questions of probability. While these philosophical aspects delve into whether our actions are predetermined or free, they are separate from the mathematical and applied concept of probability, which is a tool for dealing with uncertainty across various domains.
