dua dadu dilambungkan sekaligus peluang muncul jumlah kedua mata dadu bilangan prima adalah

jumlah bil 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)=15/36=5/12

(1,2)(1,4)(1,6)
(2,1)(2,3)(2,5)
(3,2)(3,4)
(4,1)(4,3)
(5,1)(5,2)(5,6)
(6,1)(6,5)
n(a) =15
n(s) =36
p(a)= 15/36
= 5/ 12

semoga membantu
