dadu berjumlah 10 : (4,6),(5,5),(6,4) maka n(a) = 3
P(jmlh 10) = 3/36
dadu berjumlah 9: (3,6),(4,5),(5,4),(6,3) maka n(a) = 4
P(jmlh 9) = 4/36
P(jmlh 10 atau 9) = 3/36 + 4/36 = 7/36
frekuensi harapan jmlh 10 atau 9 = 7/36 x 6000 = 1400
mata dadu berjumlah 10 = (4+6), (5+5), (6+4)
n(A) = 3
mata dadu berjulah 9 = (3+6), (4+5), (6+3), (5+4)
n(B) = 4
P (A dan B) = P (A ∩ B) = P (A) × P (B)
= 3/36 × 4/36
= 1/12 × 1/9
= 1/108
F(h) = P(A∩B) × N
= 1/108 × 6000
= 500/9
= 55 5/9 kali
