Assess understanding of definitions and basic relationships among almost sure convergence, convergence in probability, convergence in L^p (p≥1), and convergence in distribution. Students will identify which mode holds for short example sequences, give simple proofs or counterexamples of standard implications (a.s. ⇒ in probability ⇒ in distribution; L^p ⇒ in probability under integrability), and verify expectation limits where relevant.
