Question

Dua buah dadu dilempar n(s)= 6, tentukan
P(jumlah prima)
P(jumlah ganjil)
P(2,3)
P(jumlah genap)

Answer 1

Dua dadu = 6.6 = 36


jmlh prima = (1,1);(1,2);(1,4);(1;6);(2,1);(2,3);(2,5);(3,2);(3,4);(4,1);(4,3);
(5,2);(5,6);(6,1);(6,5) ----> n = 15
jadi, P = 15/36



jumlah ganjil =
(1,2);(1,4);(1,6);(2,1);(2,3);(2,5);(3,2);(3,4);(3,6);(4,1);(4,3);
(4,5);(5,2);(5,4);(5,6);(6,1);(6,3);(6,5) ----> n = 18
jadi, P = 18/36 = 1/2



P(2,3) = 1/36



jumlah genap =
(1,1);(1,3);(1,5);(2,2);(2,4);(2,6);(3,1);(3,3);(3,5);(4,2);(4,4);
(4,6);(5,1);(5,3);(5,5);(6,2);(6,4);(6,6) ----> n = 18
jadi, P = 18/36 = 1/2
