Hey, I am really stuck on a question so if anyone can help me I would be very grateful.
Show that the set of finite unions of closed intervals in has the f.i.p.
I know that for a collection of sets to have the finite intersection property means that each nonempty finite subcollection of these sets has a nonempty intersection.
But I am unsure how to do this question and how to set it out.
Thanks in advance for any help.
