P = { x 15 < x < 19,x bilangan prima}
Q = { x 19 < x < 20, x bilangan ganjil }
Maka PnQ adalah …
A. { 13, 13, 17 }
C. {9,11,13,17,19}
B. (11.13.17.19)
D. (5.79.11.13.15.17.19)

Tolong dengan caranya juga​

Jika diketahui :

Jawaban:

jawab =

1.) tentukan anggota dari setiap himpunan

S = {bilangan asli kurang dari 15}

→ S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}

P = {x I 3 < x < 15, x ∈ bilangan prima}

→ P = {5, 7, 11, 13}

Q = {x I 3 < x < 15, x ∈ bilangan ganjil}

→ Q = {5, 7, 9, 11, 13}

2.) jawablah soal dengan teliti dan tepat

anggota P

→ P = {5, 7, 11, 13}

anggota Q.

→ Q = {5, 7, 9, 11, 13}

P ∪ Q

→ P ∪ Q = {x I x ∈ P dan x ∈ Q}

→ P ∪ Q = {5, 7, 9, 11, 13}

P ∩ Q

→ P ∩ Q = {x I x ∈ P atau x ∈ Q}

→ P ∩ Q = {5, 7, 11, 13}

P' U Q'

→ P' = {1, 2, 3, 4, 6, 8, 9, 10, 12, 14}

→ Q' = {1, 2, 3, 4, 6, 8, 10, 12, 14}

→ P' ∪ Q' = {1, 2, 3, 4, 6, 8, 9, 10, 12, 14}

itu jawabannnya kan
