Saya coba bantu jawab yah !Penyelesaian :
--------------------
Diket : Bnyk lemparan = 180 kali
Kemungkinan mata dadu selisih 2
= (1, 3) , (3, 1) , (2, 4) , (4, 2) , (5, 3) , (3, 5), (6, 4), (4,6) --> n (A) = 8
Total kemungkinan n (S) = 36
Frekuensi Harapan
= n (A) / n (S) × Bnyk lemparan
= 8/36 × 180
= 8 × 180/36
= 8 × 5
= 40 kali
Maka , frekuensi harapan munculnya mata dadu selisih dua adalah 40 kali
Semoga bisa membantu yah

Selisih kedua mata dadu 2=> A = {(1,3),(2,4),(3,1),(3,5),(4,2),(4,6),(5,3),(6,4)}
=> n(A) = 8
Dua dadu
S = 6 × 6
S = 36
n(S) = 36
Dilempar sebanyak 180 kali
P = n(A)/n(S) × 180
P = 8/36 × 180
P = 40
Jadi frekuensi harapan muncul selisih kedua mata dadu 2 adalah 40 kali
