Let X take on values −2, −1, 1, 2 each with probability 0.25. Let Y = X^2 , so that Y takes on values 1, 4 each with probability 0.5. Clearly, since Y is defined in terms of X, then Y is dependent on X. You can show quickly that Cov(X, Y ) = 0, and as a consequence, that ρ = 0. These random variables are uncorrelated, yet dependent.
