Dua dadu dilempar secara bersamaan sekali. Peluang dadu pertama muncul mata dadu genap dan dadu kedua muncul mata dadu prima adalah?

A = muncul dadu pertama genap dan dadu kedua prima
A = {(2,2),(2,3),(2,5),(4,2),(4,3),(4,5),(6,2),(6,3),(6,5)}------>n(A) = 9
n(S) = {(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),(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(S)= 36

P(A) = n(A)/n(S)
P(A) = 6/36 = 1/6

Moga membantu...
