On the right-hand side, the first term converges to zero as ''n''&nbsp;→&nbsp;∞ for any fixed ''δ'', by the definition of convergence in probability of the sequence {''X<sub>n</sub>''}. The second term converges to zero as ''δ''&nbsp;→&nbsp;0, since the set ''B<sub>δ</sub>'' shrinks to an empty set. And the last term is identically equal to zero by assumption of the theorem. Therefore, the conclusion is that

\lim_{n\to\infty}\Pr \big(\big|g(X_n)-g(X)\big|>\varepsilon\big) = 0,

at each point ''X''(''ω'') where ''g''(·) is continuous. Therefore,
