Diketahui s = {×|×9 × bilangan asli } a = { 1 2 3 4 5 } dan b { bilangan prima dalam s}
Jawaban:
S = {1,2,3,4,5,6,7,8,9}
A = {1,2,3,4,5}
B = {2,3,5,7}
Jawab
a.
S = {1,2,3,4,5,6,7,8,9}
A' = {1,2,3,4,5}'
= {6,7,8,9}
B' = {2,3,5,7}'
= {1,6,8,9}
b. A ∩ B = {1,2,3,4,5} ∩ {2,3,5,7}
= {2,3,5}
c. A U B = {1,2,3,4,5} U {2,3,5,7}
= {1,2,3,4,5,7}
d. A – B = {1,2,3,4,5} – {2,3,5,7}
= {1,4}
e. (A ∩ B)' = {2,3,5}'
= {1,4,6,7,8,9}
f. (A U B)' = {1,2,3,4,5,7}'
= {6,8,9}
