dua dadu dilempar sati kali. peluang muncul pasangan mata dadu berjumlah kelipatan 3 adalah

Kelipatan 3 = 3, 6, 9, 12...
Jumlah kedua dadu = 12
n(S) = 36 {12 x 3)

Peluangnya;
= 12/36
= 1/3

Maaf kalau salah

n = (1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1),(5,2), (5,3), (5,4), (5,5), (5,6). (6,1), (6,2), (6,3), (6,4), (6,5), (6,6)
n = 36
kelipatan 3 = (3,3), (3,6), (6,3), (6,6)
n (kelipatan 3) = 4
n (s) = 4/36
n (s) = 1/9
