pada pelemparan dua buah dadu secara bersamaan, tentukan peluang muncul mata dadu berjumlah : a. 3 dan 8 b. 4 dan 12 c. 2 dan 6

n(S) = 6² = 36

a) jumlah 3 = (1,2)(2,1) , n(A) = 2
jumlah 8 = (2,6)(3,5)(4,4)(5,3)(6,2) , n(A)=5
total n(A) = 2 + 5 = 7
n(P) = 7/36

b) jumlah 4 = (1,3)(2,2)(3,1) , n(A) = 3
jumlah 12 = (6,6) , n(A) = 1
total n(A) = 3 + 1 = 4
n(P) = 4/36 = 1/9

c) jumlah 2 = (1,1) , n(A) = 1
jumlah 6 = (1,5)(2,4)(3,3)(4,2)(5,1) , n(A)=5
total n(A) = 1 + 5 = 6
n(P) = 6/36 = 1/6
