diketahi p ={ bilangan cacah kurang dari 8 },Q= bilangan prima kurang dari 10 },dan R = { faktor dari 20 }.Dengan menulis angota anggotanya tentukan: a.P U Q b.

DIKETAHUI :
P = {0,1,2,3,4,5,6,7}
Q = {2,3,5,7}
R = {1,2,4,5,10,20}
JAWAB :
a. P U Q = {0,1,2,3,4,5,6,7}
b. Q U P = {0,1,2,3,4,5,6,7}
c. Q U R = {1,2,3,4,5,7,10,20}
d. (P U Q) U R = {0,1,2,3,4,5,6,7,10,20}
e. P U (Q U R) = {0,1,2,3,4,5,6,7,10,20}
