Tentukan n(A irisan B)
b. n(P)=28,n(Q)=27,P irisan Q =
{ }.Tentukan n (P U Q)
c. n(K)=59,n(L irisan K)= 13,n(K U L)=110.
Tentukan n(L)
A. n(A)=35 ,n(B)=29 ,n(A U B)=50.
Jawaban Terkonfirmasi
A.
n(A u B) = n(A) + n(B) – n(A n B)
50 = 35 + 29 – n(A n B)
n(A n B) = 35 + 29 – 50 = 14
b.
n(P u Q) = n(P) + n(Q) – n(P n Q) = 28 + 27 – 0 = 55
c.
n(K u L) = n(K) + n(L) – n(L n K)
110 = 59 + n(L) – 13
n(L) = 110 – 59 + 13 = 64
