呢課真係好難可能連埋probability一起出一題1X分
分辨5/5*/5**

我未學probability
但以M1 泥講
nPr同nCr
係第1課咋wo/
之後仲有 d .. in ... -__-

我覺得d仲易過p同c

d 初頭就易
後尾複雜D就唔係背公式咁簡單 (個人感覺)

以會考為例,長題目有五大類型
1)概率
2)變分
3)等差,等比
4)圓形,坐標
5)線性規劃

會考既概率其實好淺,所以dse基本上 nPr nCr同概率炒埋一碟,實行將lv 5 5* 5** 分高下~

In the new syllabus, the marks of each question in Section B is no longer fixed.
Section B may contain both short and long questions.

Permutation and combination is in the non-foundation part so it will certainly be in Section B (unless it is not examined).
However, I think it may be a relatively short question because there are more important topics in the non-foundation part.

I agree with that.

I find permutation and combination even harder than distributions of random variables.

You missed an important topic.

我覺得nPr nCr同probability好易炸喎..

難定易睇HKEAA點出姐
呢個topic一樣可以出得好難，3x年前既pure maths就有呢D問題

因為p 同c 係睇個腦轉數
其他數 你做得熟基本上都岩硬

You need to think very carefully in these questions.

A small change in wordings will give a completely different answer.

實會 佢好似跟會考個d形式出咁

d and In is quite easy, but nPr and nCr is quite hard
