I don't think it is easy in general. May8 comment Distribution of composite numbers And by the looks of it anyone who reads this is going to gain a lot. May8 comment Distribution of composite numbers No pain no gain. May8 comment Why is the open interval $(0, 1)$ a Polish space? Are countries starting to claim territory in the real number line now too? This is preposterous ! May8 answered How long will it take for one of them or both of them?
