Let X be a random variable, and {Xn}1 a sequence of random variables, on a probability space (N,F,P). (a) Define what it means for the sequence of random variables {X} to converge to X in probability? nfn=1 (b) Define what it means for the sequence of random variables {X₂} to converge to X almost surely (a.s.)? (c) Prove that if {Xn}1 converges to X a.s. then {Xn} converges to X in prob- ability.
