In statistics, a fundamental concept found in the introduction to probability. When dealing with the introduction to probability, students first encounter basic problems that calculate the likelihood of an event occurring, an event such as drawing a specific card from a deck. Terms from an introduction to probability include an event, its complement and the sample space.
