...But I can't get it
We have a sequence of iid nonnegative rv's
Assuming that is finite, we have by the sLLN that converges to a finite limit.
But how can I conclude that ?
I tried to relate it to the series , but the inequality is the other way round than the one that would be helpful...
...so since inequalities don't help me, I hope you guys can help me
Note : I also - miserably - tried CesÓro's mean.
