Kelas 9 Matematika
Bab Peluang

a] Kartu AS ada 4

Peluang = 4/52
Peluang = 1/13

b] Kartu bernomor ganjil = { 1, 3, 5, 7, 9 }
n = 5

Banyak kartu hitam bernomor ganjil
= 2 . 5
= 10

Peluang = 10/52
Peluang = 5/26

a.

kartu As
-------------
kartu brigadir

peluang = 4/52 = 1/13

b

bil. ganjil = [ 2,3,5,7,9 ]
n = 5
hitam bil.ganjil
2.5 = 10

peluang
= 10/52
= 5/26
