Question

Tolong dibantu nomor 1 sampai 4 Please ^-^

Answer 1

Himpunan
1a.
P = (1,2,3,4,5)
Q = (-4,-3,-2,-1,0)
P ∩ Q  = { }
n(P∩Q) = 0

1b.
P = (1,3,5,7)
Q= {2,3,5,7}
P∩Q= {3,5,7}
n (P∩Q)= 3

1c.
P = {b,u,n,d,a}
Q= (i,b,u )
P∩Q = {b, u}
n (P∩Q) = 2

2) K = (-2,-1,0,1,2)
L = (0,1,2,3,4)
M =(1,2,3,4)
KUL = (-2,-1,0,1,2,3,4)
KUM =(-2,-1-,0,1,2,3,4}
LUM = (0,1,2,3,4)

3) 
a) A = (0,1,2,3,4)
B = (1,3,5,7)
C =(2,3,5,7,11)

b) AUB = (0,1,2,3,4,5,7)
c) BUC = (1,2,3,4,5,7,11)
d). A U (BUC) = (0,1,2,3,4,5,7,11)

4)  A= (0,1,2,3,4,5,6,7}
B = {5,6,7,...,14}

a) Ac = (8,9,10,11,12,13,14}
b) Bc = (0,1,2,3,4}
c)  (A∩B)c = (0,1,2,3,4,8,9,10,11,12,13,14}
d) (AUB)c = { } = ∅
