Question

13. Diketahui himpunan P dan Q berikut. P = {x|4 < x < 20, x kelipatan 3} Q = {x|4 ≤ x ≤ 15, x bilangan genap} Hasil dari P UQ adalah.... A. {6, 12} B. {6, 12, 15} C. (4, 6, 8, 9, 10, 12, 14, 15, 18) (2, 4, 6, 8, 9, 10, 12, 14, 15, 18} D.​

Answer 1

Jawab:
PUQ = {4, 6, 8, 9, 10, 12, 14, 15, 18}

Penjelasan dengan langkah-langkah:
P =      {6,   9,    12,     15, 18}
Q = {4, 6, 8, 10, 12, 14}
PUQ gabung semua
PUQ = {4, 6, 8, 9, 10, 12, 14, 15, 18}
