2 buah dadu bermata 6 dilempar sekali secara bersamaan peluang munculnya jumlah 2mata dadu kurang dari 10 adalah

N(S) = 6² = 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), (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (5, 1), (5, 2), (5, 3), (5, 4), (6, 1), (6, 2), (6, 3) » 30

p(A) = 30/36 = 5/6

semoga membantu
