Penjelasan dengan langkah-langkah:
Himpunan bagian adalah himpunan yang anggotanya merupakan bagian dari suatu himpunan.
Banyaknya himpunan bagian dapat dihitung dengan rumus 2^n, dengan n adalah banyaknya anggota himpunan.
Tentukan himpunan bagian dari himpunan-himounan berikut!
a. A = {2, 3, 4, 5}
n = 4
Himpunan bagian dari A :
{2,3,4,5}, {2,3,4}, {2,3,5}, {2,4,5}, {3,4,5}, {2,3}, {2,4}, {2,5}, {3,4}, {3,5}, {4,5}, {2}, {3}, {4}, {5}, {}
Banyaknya himpunan bagian dari A =
= 2^n
= 2^4
= 16 ✔️ (Terbukti, jika kalian hitung himpunan bagian di atas, banyaknya himpunan bagian dari A adalah 16 himpunan)
b. B = {bilangan asli kurang dari 7}
B = {1, 2, 3, 4, 5, 6}
n = 6
Himpunan bagian dari B :
{1,2,3,4,5,6}, {1,2,3,4,5}, {1,2,3,4,6}, {1,2,4,5,6}, {1,2,3,5,6}, {1,3,4,5,6}, {2,3,4,5,6}, {1,2,3,4}, {1,2,4,5}, {1,2,5,6}, {1,2,3,5}, {1,2,3,6}, {1,2,4,6}, {1,3,4,5}, {1,3,5,6}, {1,3,4,6}, {1,4,5,6}, {2,3,4,5}, {2,3,4,6}, {2,3,5,6}, {2,4,5,6}, {3,4,5,6}, {1,2,3}, {1,2,4}, {1,2,5}, {1,2,6}, {1,3,4}, {1,3,5}, {1,3,6}, {1,4,5}, {1,4,6}, {1,5,6}, {2,3,4}, {2,3,5}, {2,3,6}, {2,4,5}, {2,4,6}, {2,5,6}, {3,4,5}, {3,4,6}, {3,5,6}, {4,5,6}, {1,2}, {1,3}, {1,4}, {1,5}, {1,6}, {2,3}, {2,4}, {2,5}, {2,6}, {3,4}, {3,5}, {3,6}, {4,5}, {4,6}, {5,6}, {1}, {2}, {3}, {4}, {5}, {6}, {}
Banyaknya himpunan bagian dari B =
= 2^n
= 2^6
= 64 ✔️ (Terbukti, jika kalian hitung himpunan bagian di atas, banyaknya himpunan bagian dari B adalah 64 himpunan)
