Unformatted text preview: sets like in (*), constructed from unions, intersections, and setcomplements. Solution 2 : Starting with the 3 sets in this example, the Venn diagram has 2 3 = 8 regions: R1, . .. R8. See below. From the diagram, the set on the LHS of (*) consists of the regions { R1, R4 }∩{ R4,R7 }={ R4 } . The set on the RHS of (*) consists of the regions { R4, R5 }− { R2,R3,R5,R6 }= { R4 } . Thus, the sets on the LHS and RHS both consist exactly of the same region, namely R4. Thus, the LHS & RHS sets are the same. A B C R1 R2 R3 R4 R5 R6 R7 R8...
