Question:
Non-measurable sets (1). Let \(\mu\) be a measure on \(\mathscr{A}=\{\emptyset,[0,1),[1,2),[0,2)\}, X=[0,2)\), such that \(\mu([0,1))=\mu([1,2))=\frac{1}{2}\) and \(\mu([0,2))=1\). Denote by \(\mu^{*}\) and \(\mathscr{A}^{*}\) the outer measure and \(\sigma\)-algebra which appear in the proof of Theorem 6.1 .
(i) Find \(\mu^{*}(a, b)\) and \(\mu^{*}\{a\}\) for all \(0 \leqslant a
(ii) Show that \((0,1),\{0\} otin \mathscr{A}^{*}\).
Data from theorem 6.1
