機率

(已重新導向自 機率)

歷史

Cardano的數學著作中有很多給賭徒的建議。這些建議都寫成短文。例如：《誰，在什麼時候，應該賭博？》、《為什麼亞里士多德譴責賭博？》、《那些教別人賭博的人是否也擅長賭博呢？》等。

概念

「從一班40名學生中隨意選出一人，這人會是男生嗎？」

數學處理

1. 非負性：$P(A) \geq 0$
2. 規範性：$P( \Omega ) = 1$
3. 可數可加性：對可數個兩兩互斥事件{Ai}i∈N有：${\displaystyle\sum_{i=1}^{\infty}P(A_{i})=P\left( \bigcup_{i=1}^{\infty}A_{i}\right)}$

機率計算總結

A $P(A)\in[0,1]\,$

A或B \begin{align} P(A\cup B) & = P(A)+P(B)-P(A\cap B) \\ P(A\cup B) & = P(A)+P(B) \qquad\mbox{if A and B are mutually exclusive} \\ \end{align}
A和B \begin{align} P(A\cap B) & = P(A|B)P(B) = P(B|A)P(A)\\ P(A\cap B) & = P(A)P(B) \qquad\mbox{if A and B are independent}\\ \end{align}
B的情況下A的機率 $P(A \mid B) = \frac{P(A \cap B)}{P(B)} = \frac{P(B|A)P(A)}{P(B)} \,$
