Marginal probability refers to the probability of an event occurring irrespective of the outcomes of other variables, essentially summing or integrating over the probabilities of the other variables. It is a fundamental concept in probability theory and statistics, often used in the context of joint probability distributions to extract the probability of a single event or variable.

Marginal probability

The probability of an event is a measure of the likelihood that the event will occur, expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. It is a fundamental concept in statistics and mathematics, providing a quantitative description of the expected frequency of outcomes in a random experiment.
