20. Given a set N = {1,2,3,4}. Find P(S).

Answer 1

11)A = {a,c,e,g} and B = {d, e, f, g}

A ∪ B={a,c,d,e,f,g}

====================================================

12)A = {a,c,e,g} and B = {d, e, f, g}.

A ∩ B   ={e,g}

-------=================================================

14)s={0,1,2}

{ },{0},{1},{2},{0,1}{0,2}{1,2},{1,2,3}
