tolong ya di kasih jawaban !!! di kumpulin hari Senin.

1. P = {7, 11,13,17,19}
Q= {1,3,5,7,9,11,13,15}
R = {3,6,9,12,15,18}
2. A = {2,3,5,7}
B = {1,3,5,7,9}
C = {3,4,5,6,7,8,9}
a. A n B = {3,5,7}
b. A n C = {3,5,7}
c. B n C = {3,5,7,9}
d. A n B n C = {3,5,7}
3. a. P - Q = {c}
b. Q - P = {b,q}
c. Q - R = {b,f,q}
d. R - Q = {a,e,g}
4. S = {1,2,3,4,5,6,7,8,9}
A = {2,3,5,7}
B = {5,7,9}
a. A^c = {1,4,6,8,9}
b. B^c = {1,2,3,4,6,8}
c. A n B = {5,7}
(A n B)^c = {1,2,3,4,6,8,9}
d. A u B = {2,3,5,7,9}
(A u B)^c = {1,4,6,8}
