Math Problem Analysis

Mathematical Concepts

Probability Theory
Covariance
Joint Probability
Independence

Formulas

Cov(X,Y) = E[XY] - E[X]E[Y]
E[X] = Σ x * p(x)
E[Y] = Σ y * p(y)
Independence condition: p(x, y) = p_X(x)p_Y(y)

Theorems

Uncorrelated Variables: Cov(X,Y) = 0
Independence of Variables: Joint distribution equals the product of marginals
