Dua buah dadu dilambungkan sekali secara bersamaan, peluang muncul jumlah kedua mata dadu bukan faktor prima dari 90 adalah.. cepat di jawab

Jumlah dadu bukan prima = (1,3),(1,5),(2,2),(2,4),(2,6),(3,1),(3,3),(3,5),(3,6),(4,2),(4,4),(4,5),(4,6),(5,1),(5,3),(5,4),(5,5),(6,2)(6,3),(6,4),(6,6) ada 21
P = 21/36 = 7/12
F.harapan = 7/12 x 90 = 52 1/2

jumlah dadu bukan prima = jumlah dadu yg jumlahnya 4,6,8,9,10,12,
junitanjungkedua mata dadu yg bukan faktor prima dari 90=A {1,3},{1,5},{1,6},{2,2},{2,4},{2,5},{2,6},{3,1},{3,3},{3,4},{3,5},{3,6},{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(A)=29
ada 21
P = 21/36 = 7/12
F.harapan = 7/12 x 90 = 52 1/2
{1,3},{1,5},{1,6},{2,2},{2,4},{2,5},{2,6},{3,1},{3,3},{3,4},{3,5},{3,6},{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(A)=29
P=n(A)/ n(s)=29/36
