Question

Buatlah poster hubungan yg terjadi antara himpunan a dan himpunan b jika diketahui bahwa:
(maksudnya gmn?)
1. A U B=A
2. A n B=B
3. A U B = ∅
4.A n B=A
5.A n B = B
6. A n B =∅
7. A-B= A
8. A-B =∅

Answer 1

1. A. AUB =A contoh soal
A{1,2,3,4,5,6,7,8,9,10}
B{2,4,6,8}
AUB ={1,2,3,4,5,6,7,8,9,10} (bikin diagram ven nya)

2. B. AUB=B contoh soal
A {1,5,9,13}
B{1,3,5,7,9,11,13}
AUB=B {1,3,5,7,9,11,13}. (bikin diagram venya)

3.C. AUB=0 coret
A{ }
B{ } (bikin diagram ven satu lingkaran kosong)

4. D.A n B = A
A{4,6,8,10}
B{4,8}
A n B ={4,8} (bikin diagram ven )

5.E. A n B = B
A {1,3,5,7,9,11}
B{1,3,5,7,9,11}
A n B = {1,3,5,7,9,11}. (bikin diagram venn )

6. F .A n B = 0 coret
A{ kambing ,sapi,kuda }
B {ayam ,bebek,angsa}
A n b = 0 coret (bikin diagram ven )

7. G. A- B = A
A {2,4,6,8,10,12}
B {,4,6,8,10}
A-B={12} (bikin diagram ven )

8. H. A-B =0 coret
A{1,2,3,4,5,6}
B{1,2,3,4,5,6}
A-B = { } Bikin diagram
