Let (R, B, P) be a probability space, where P is some given probability measure. For n = 2, 3, … , define En = (an, bn) where(adsbygoogle = window.adsbygoogle || []).push({});

an = min { 1/n , (-1)^n + 1/n } and bn = max { 1/n , (-1)^n + 1/n }

Write the events {En i.o.} and {En almost always}.

i.o. = infinitely often

Need help with this... it means that {En i.o.} = {(-1)^n} since its going to be in the limsup, and {En almost always} = {1/n}?
