Dua dadu ditos bersama-sama, peluang muncul mata dadu pertama bukan bermata 3 adalah...

n(s) = 6^2 = 36
n(a) = {(1,1) (1,2) (1,3) (1,4) (1,5) (1,6) (2,1) (2,2) (2,3) (2,4) (2,5) (2,6) (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)} = 30

P(a) = n(a) / n(s)
P(a) = 30 / 36
P(a) = 5 / 6
