dua buah dadu di lambungkan bersama sama satu kali berapakah peluang muncul jumlah prima?

(1+1) (1+2) (1+4) (1+6) (2+3) (2+5) (3+4) (5+6) = 8
(1+1)(1+2)(1+3)(1+4)(1+5)(1+6)(2+2)(2+3)(2+4)(2+5)(2+6)(3+3)(3+4)(3+5)(3+6)(4+4)(4+5)(4+6(5+5)(5+6)(6+6) = 21
=8/21

jumlah prima=(1,1)(2,1)(1,2)(2,3)(3,2)(1,4)(4,1)(2,5)(5,2)(3,4)(4,3)(1,6)(6,1)(5,6)(6,5)
n(s)= 6^2=36
peluang= 15/36= 5/12
maaf kalau salah
