Verified answer

Kelas 9 Matematika
Bab Peluang

Jumlah titik sampel 2 mata dadu
= 6²
= 36

Jumlah mata dadu 2 = { (1, 1) }
n = 1

Jumlah mata dadu 3 = { (1, 2), (2, 1) }
n = 2

Jumlah mata dadu 5 = { (1, 4), (4, 1), (2, 3), (3, 2) }
n = 4

Jumlah mata dadu 7 = { (1, 6), (6, 1), (5, 2), (2, 5), (3, 4), (4, 3) }
n = 6

Jumlah mata dadu 11 = { (5, 6), (6, 5) }
n = 2

Peluang = (1 + 2 + 4 + 6 + 2)/36
Peluang = 15/36
Peluang = 5/12
