Jawaban:
A. (i) dan (iii)
Penjelasan dengan langkah-langkah:
S = {Sepuluh bilangan cacah pertama}
A = {x | 5 < x ≤ 9, x ∈ bilangan asli}
B = {x | 0 ≤ x ≤ 8, x ∈ bilangan prima}
S = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
A = {6, 7, 8, 9}
B = {2, 3, 5, 7}
Pernyataan:
(i) A ∩ B = {7}
A = {6, 7, 8, 9}
B = {2, 3, 5, 7}
A ∩ B = {7}
(ii) A ∪ B = {2, 3, 5, 6, 7, 8}
A = {6, 7, 8, 9}
B = {2, 3, 5, 7}
A ∪ B = {2, 3, 5, 6, 7, 8, 9}
(iii) A - B = {6, 8, 9}
A = {6, 7, 8, 9}
B = {2, 3, 5, 7}
A - B = {6, 8, 9}
(iv) A - Bᶜ = {0, 1, 4}
A = {6, 7, 8, 9}
B = {2, 3, 5, 7}
Bᶜ = {0, 1, 4, 6, 8, 9}
A - Bᶜ = {7}
Pernyataan yang benar:
(i), (iii)
A. (i) dan (iii)
