Question

Diberikan S = {1,2,3,4,5,6,7,8,9,10}
A={1,2,3,4,5}
B={4,5,6,7,8}
C={3,5,7,9}
Tentukan :
a. Ac U (BnC)
b.(AnB) n Cc
c. (B - C) n A

Answer 1

1. Ac={6, 7,8,9,10}
    B n C = {5, 7)
    Ac U (B n C) = { 5,6, 7,8,9, 10}
2. Cc ={{1, 2, 4, 6, 8, 10}
   A n B = { 4, 5}
   (A n B) n Cc = {4}
3. B - C = {4, 7, 8}
   (B - C) n A = {4}
