One of the conditions for a measure, m, is that if then .
Thanks a lot I want to ask another thing related to it that how can we prove Phy belongs to Rn Where Rn denotes all null subsets of algebra R
What do you mean by "Phy"?
greek work phy means null or empty...

Sorry for the typo mistake Thanks
In any case the empty set is a subset of every set and certainly has measure 0, therefore is in Rn.
