This document discusses privacy and provides a mathematical formula for calculating privacy based on effort, knowledge, and awareness. It defines privacy as separation from a group or environment and notes that privacy depends on the amount of effort put into mitigation actions, one's knowledge of privacy concepts and technologies, and overall awareness of how one's data is exposed. The document presents examples of how different combinations of these factors can result in higher or lower levels of privacy. It encourages increasing effort, knowledge, and awareness to improve privacy according to the formula P=E(K+A).
