peluang muncul dua muka yg bernomor ganjil pada percobaan pelemparan dua buah dadu sekali

Dua buah dadu
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
A=peluang muncul kedua mata dadu ganjil
A={(1,1)(1,3)(1,5)(3,1)(3,3)(3,5)(5,1)(5,3)(5,5)}
n(A)=9
P(A)=n(A)/n(S)
=9/36
=1/4

Semoga bisa membantu...
