Random bisa dengan :

1. RandBetween (hasilnya bilangan bulat) -> random 1 nilai yang ada di rentang nilai a dan b, 

     misal =RandBetween( 10 , 40 ), hasilnya 1 angka random seperti 31 atau lainnya (yang ada di rentang 10 s.d. 40)

2. Rand (hasilnya bilangan desimal [ada angka di belakang koma]) -> random 1 nilai yang ada di rentang nilai 0 dan 1

    jika ingin hasil random di rentang a dan b (seperti nomor 1), dengan Rand() * (b-a) + a

Kasus ini :

misal angka 150 ingin dipecah jadi 5 bijik angka random, maka :

hitung dulu reratanya, misal 150/5 = 30, berarti random disekitar angka 30, misal di rentang 25 s.d. 30, artinya

angka random ke-1 : =randbetween( 25,30 )   atau   =rand()*( 30-25) + 25

lalu hitung sisanya = 150-angka random ke-1, misal sisa 118/4

sisa slot random ada 4 bijik, rerata di 4 slot ini = 118/4

angka random ke-2 : =randbetween( 118/4 - 5 , 118/4 )     atau   rand()*5+118/4

dst sampai didapat angka random ke-4 (sampai bersisa 1 slot terakhir)

slot terakhir =150-sum( semua angka random yang sudah didapat)

sila dibuat sendiri formulanya di cells.

Kid
