Assume that two sequences of random variables Xn
and Yn, which converge in mean square to the
random variables X and Y , respectively.
a. Let Vn aXn and Wn = BYn. Do the sequences {Vn}
and {Wn} converge individually in mean square?
Either prove that they always converge in mean-
square sense and provide the limit, or find counter-
examples that show that they do not always converge
in mean- square sense.
b. Let us construct a sequence Un = aXn + BYn. Does
the sequence Un converge in mean square sense?
Either prove that it always converges in mean-square
sense and provide the limit, or find a counter-
example that shows that it does not always converge
in mean-square sense.
