Answer 2

13)
A = { 1, 2, 3, 4, 5 }
B = { 4, 5, 6, 7, 8 }
A' U B = ?
karena A = { 1, 2, 3, 4, 5 }, maka A' = { 6, 7, 8, 9, 10}. sehingga:
A' U B = { 4, 5, 6, 7, 8, 9, 10 }

14)
Y = { 7, 11, 13, 17, 19}
n(Y) = 5
Banyak himp bagian Y = 2^n(Y) = 2^5 = 32

15)
(A - B) n B = ?
A - B = { 1, 2, 3 } - { 3, 4, 5, 6 }
= { 1, 2 }
Jadi,
(A - B) n B = { 1, 2 } n { 3, 4, 5, 6 }
= { }

16)
A = { 1, 2, 3, 4 }
B = { 2, 3, 5 }
C = { 2, 3, 4, 5, 6, 7 }
(A U B) n C = ?
A U B = { 1, 2, 3, 4 } U { 2, 3, 5 }
= { 1, 2, 3, 4, 5 }
Jadi,
(A U B) n C = { 1, 2, 3, 4, 5 } n { 2, 3, 4, 5, 6, 7 }
= { 2, 3, 4, 5 }
