dua dadu di lempar bersama sama sebanyak 72 kali.frekuensi harapan muncul mata dadu berjumlah 5 aatau 7 adalah

langsung aja y

2 dadu
n(s) = 36
n(a) = {(1,4)(2,3)(3,2)(4,1)(1,6)(2,5)(3,4)(4,3)(5,2)(6,1)} = 10

p(a) = n(a) / n(s) = 10/36

Fh = p(a) × n
Fh = 10/36 × 72
Fh = 10 × 2
Fh = 20

semoga berguna +_+
