概率:计算相对数
一.
抽样:
不可放回:sampling without replacement
1. 一次性抽取:T12,T17,T19,T22,T23,T24,T46
2. 依次抽取抽取:
第k次抽到的概率:T36
抽奖问题:
Eg:10张彩票,有一张奖票,人们依次抽出,则每个人中奖的概率相同。
1st:P=1/10
2nd: P=9/10 1/9
3rc: P=9/10 8/9 1/8
几何概率:T14
其他:T16,T17, T25,T26,T31
可放回:sampling with replacement
Eg:10张彩票,2张奖票,重复抽样,一个人连续重复抽样3次,每次都中奖的概率?
其他:T13,T15
二.
伯努利概型:
【前提】:独立重复试验
三.
涉及排列组合的:T20,T21,T34,T35
四.
其他:T28,T29,T30,T18,T50
