✔ Mapel = Matematika
✔ Kelas = 8 SMP
✔ Materi = Statistika dan Peluang
----------------------
Penyelesaian :
----------------------
37. Rata rata
= (3.2 + 4.3 + 5.4 + 6.5 + 7.3 + 8.2 + 9.1) / (2+3+4+5+3+2+1)
= (6 + 12 + 20 + 30 + 21 + 16 + 9) / 20
= 114/20
= 5,7

Bny siswa diatas 5,7
= 5 + 3 + 2 + 1 siswa
= 11 siswa

39. Peluang Mata koin Angka
= n/N
= 25/100
= 1/4

40. Ruang Sampel = 6² = 36
n(10) = {(6,4), (5,5), (4,6)} ➡ 3

Peluang
= n(10) / Ruang sampel
= 3 / 36
= 1 / 12

Semoga Membantu :)
