(book 1.20) Show that, if E1, E2, ..., Ex are mutually independent, then so are Ēj, Ē2, ..., Ēk. Which of the following arguments proves the claim? (A 1 B means A, B are independent). (a) Ilie PrcĒ;) = [1/(1 – Pr(E;)) = 1 – Pr (U, E;) = Pr(U, E;) = Pr (n; Ē;) (b) E; IE; Ē; 1 Ē; for i, jel = claim (c) Pr(Ē;) = (1 - Pr(E;)) = liel Pr(Ē;) = Pr( i E;) (d) Pr(Uiel E;) = Liel Pr(E;) for disjoint events = liel Pr( Ē;) = Pr(n; Ē;) (e) none of these
