Question

Diketahui S={1,2,3,4,5,6,7,8}
A={1,2,3,4}
B={4,5,6}
dan C={3,5,7}
*Tentukan anggota dari :
a. AU(BnC)^c
b. (A^c n B^c) n C
c. (B–C) ^c U A

Tolong bantuannya yaa..

Trims...

Answer 1

A) B n C = 4
(B n C) ^c =1, 2, 3, 5, 6, 7, 8
A u (B n C) ^c =1, 2, 3, 4, 5, 6, 7, 8

b) A^c =5, 6, 7, 8
B^c = 1, 2, 3, 7, 8
(A^c n B^c) = 7, 8
(A^c n B^c) n C = 7

c) B-C = 4, 6
(B-C) ^c = 1, 2, 3, 5, 7, 8
(B-C) ^c u A = 1, 2, 3, 4, 5 , 7, 8
