Definitions:

Independent

Not influenced by or dependent on another variable; in statistics, it often means that the occurrence of one event does not affect the probability of another event.

COV(X,Y)

Covariance between two variables X and Y, measuring the extent to which the variables change together and indicating the direction of their linear relationship.

Marginal Probability

The probability of occurring of a single event without consideration of any other events; it’s the likelihood of a single outcome.

Variance

Variance is a statistical measure that represents the degree of spread in a dataset's numbers; it quantifies how far each number in the set is from the mean and thus from every other number in the set.
