Question

Mohon dijawab kalau bs dr no1 sampai 5

Answer 1

Nomor 1
X = {2, 3, 5, 7,11,13,17}
a. 2 anggota = {2,3}, {2, 5}; {2, 7}; {2, 11}; {2, 13}. {2, 17}; {3, 5}; {3, 7}; {3, 11};      {3, 13 }; {3, 17}; {5, 7}; {5, 11}; {5, 13}, {5, 17}; {7, 11}; {7, 13}; {7, 17}; {11, 13}: {11, 17}; {13, 17} → n (2 anggota) = 21

b. 4 anggota = {2,3,5,7}; {2,3,5,13}; {2,3,5,17}; {3,5,7,13}; {3,5,7,17}: {5,7,13,17} → n (4 anggota) = 6

c.  5 anggota = {2,3,5,7,11}; {2,3,5,7,13}; {2,3,5,7,17}: {3,5,7,11,13}: {3,5,7,11,17}; {5,7,11,13, 17} → n (5 anggota ) = 6

d. 6 anggota = {2,3,5,7,11,13}; {2,3,5,7,11,17}; {3,5,7,11,13, 17};  n = 3

Nomor 2
Lihat lampiran

========================

Nomor 3

n(A ∪ B) = n(A) + n(B) - n(A ∩ B)
25 = 15 + 18 - n (A ∩ B)
n(A∩B) = 8

==========================

Nomor 4

n(A ∪ B) = n(A) + n(B) - n(A ∩ B)
               = 22 + 2 8 - 1 0
               = 40

=================================

Nomor 5
a. PR // SU ; ST//PQ;
