U = S = (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15)
C = (6,8,10,12)
D = (1,2,3,4,6,8,12,24)..(24 diluar himp U) sehingga menjadi
    = (1,2,3,4,6,8,12)

a. C' = (yang bukan anggota himp C)
        = (1,2,3,4,5,7,9,11,13,14,15)
b. Dc = (yang bukan anggota himp D)
          = (5,7,9,10,11,13,14,15)

C П D = (6,8,12)
c.  (C П D)' = (yang bukan irisan C dan D)
                  = (1,2,3,4,5,7,9,10,11,13,14,15)

d. (C П D)c = (yang bukan irisan C dan D)
                  = (1,2,3,4,5,7,9,10,11,13,14,15)
