That makes sense. Thank you!

But the $\mu$ can be infinity, I think you cannot apply strong law of large numbers. And you haven't used the condition that the variance is finite.

comment Bounded random variable
That's correct. I misunderstood the question. I thought I should find a Y for all all ε>0, P(X≠Y)<ε.

comment Bounded random variable
It's obviously Y can cover $X\,1_{\left|X\right|\leq x}$ for arbitrary x. But how do you deal with the part $X\,1_{\left|X\right|>x}$? How can it be less than any positive number when you fix a x? Thanks!

What about the part {X>x}. Could you explain a little bit more?
