begini saya mau tanya rumus untuk pencarian titik sampel pada peluang agar lebih mudah pada ujian.misal titik sampel jika pengetosan 2 mata uang dan 2 dadu yang dilempar secara bersamaan

Banyaknya ruang sampel(titik sampel) suatu kejadian = banyaknya sisi I x banyaknya sisi II. Contoh jika 1 mata uang dan 1 dadu dilempar bersamasama, maka banyaknya ruang sampel=2x6=12. Jika 2 mata uang dan 2 mata dadu dilempar bersama, maka banyaknya ruang sampel= 2x2x6x6 =144

Semoga jelas.

News Item

Ciri Kebahasaan:   Menggunakan action verbs, misalnya eat, run; binatang, benda tertentu;   Disusun Menggunakan past tense; Menggunakan keterangan waktu dan tempat;  sesuai dengan urutan kejadian.

Contoh:
Russian Nuclear Catastrophe
(Elaborasi kejadian): Moscow-A Russian journalist has uncovered evidence of another Soviet nuclear catastrophe, which killed 10 sailors and contaminated an entire town.

(Komentar saksi kejadian): Yelena Vazrshavskya is the first journalist to speak to people who witnessed the explosion of a nuclear submarine at the naval base of Shkotovo-22 near Vladivostock.
The accident, which occurred 13 months before the Chernobly disaster, spread radioactive fall-out over the base and nearby town, but was covered up by officials of the Soviet Union. Residents were told the explosion in the reactor of the Victor class sub marine during a refit had been a 'thermal' and not a nuclear explosion. And those involved in the clean-up operation to remove more than 600 tons of contaminated materials were sworn to secrecy.

(Pendapat para ahli): A board of investigators was later to describe it as the worst accident in the history of the Soviet Navy.

dalam sebuah kantong terdapat 100 buah kelereng. 48 kelereng berwarna hitam, 50 kelereng berwarna hijau,sisanya berwarna merah. apabila diambil 5 buah kelereng secara random sebanyak 50 kali. hitunglah frekuensi harapan terambil kelereng berwarna hitam semua?

Peluang terambil 5 kelereng hitam =(48X47X46X45X44):(100X99X98X97X96)

=205476480:9034502400

=0,02274353

Frekuensi harapan terambil 5 kelereng hitam

=0,02274353X50

=1,1371765

Bagaimana cara menghafal yang efektif?

Sebenarnya rumus itu jangan dihafal, tetapi harus di fahami mengapa rumus itu demikian. Sebenarnya ada caranya menghafal rumus antara lain:
 1. membuat rangkuman di buku catatan pribadi
 2. membuat "jembatan keledai" ini tergantung kreatifitas Adhik
    Contoh: Luas selimut tabung (PHEDET = PHI x d x t) dll.
    Coba adhik buat yang lain
