The primary purpose of probability theory in nursing research is to facilitate the assessment of patient outcomes. Probability theory is crucial in determining the likelihood of various outcomes when specific nursing interventions are implemented. By using probability, researchers can build models that predict how different variables and interventions may affect patients. This enables nurses and researchers to make informed decisions based on evidence, assess risks, and understand the reliability of their findings concerning patient care outcomes.

Using probability theory allows for the creation of hypotheses that can be tested statistically, which in turn helps determine the effectiveness of nursing practices and the generalizability of research results to broader patient populations. This focus on outcomes is essential to improving patient care and advancing nursing practice based on solid evidence drawn through systematic analysis. While other options are relevant to nursing research, they do not encapsulate the fundamental role of probability in comprehensively understanding and predicting patient outcomes.
