Answer 1

A. 1/12
b. 6/12= 1/2
c. 6/12= 1/2

Answer 2

5.
a.
n(satu) = 1
n(S) = 12
P(satu) = n(satu)/n(S) = 1/12
b.
n(ganjil) = 6 (Ada 1,3,5,7,9,11)
n(S) = 12
P(ganjil) = n(ganjil)/n(S) = 6/12 = 1/2
c.
n(genap) = 6 (Ada 2,4,6,8,10,12)
n(S) = 12
P(genap) = n(genap)/n(S) = 6/12 = 1/2

6.
n(S) = 3 (Hitung manual)
n(A) = 4 (Hitung manual)
n(B) = 1 (Hitung manual)
n(R) = 1 (Hitung manual)
n(S') = 14 (Hitung manual)
a.
P(S) = n(S)/n(S') = 3/14
b.
P(A) = n(A)/n(S') = 4/14 = 2/7
c.
P(B) = n(B)/n(S') = 1/14
d.
P(R) = n(R)/n(S') = 1/14
