以前可能有人有作過了 懶的找 所以自己作一個速查表
算過後 就會發現 武器60% 7張過3張 其實都還蠻合理的
因為我常這樣....
7張過2張 你就只能嘆氣了
為什麼7張過6張機率還比較高 為什麼自己運氣差到這樣
而5張過4張比還比過2張高 為什麼是過2張 而不是過4張
更別講過0/1張的去比過5張的了
請一定要相信運氣
┌────────────┐
│ 10%永遠不會過 │
│ 60%都只過一兩張 │
│ 30%卷衝必爆 │
│ 蜈蚣都給1袋錢2瓶水 │
│ 菇王都不掉卷 │
│炎盔永遠都只輪到前一位拿│
│抽小白虎 永遠都抽到1萬元│

4 3 60% 34.56000000%
4 4 60% 12.96000000%
以上是用相同卷衝的方式 我只列10/9/7/6/5/4幾種
機率算法 用Excel公式
=COMBIN(可衝卷次數,成功數)*(成功機率^成功次數*(1-成功機率)^(可衝捲次數-成功數))
數學公式
可衝卷次數 成功次數 失敗次數
C X (成功機率) X (失敗機率)
成功數
===============================================================================
以下是假設第一張10%第二張以後60%的機率
其實就是第一張用10%算 然後本來十張卷的就剩九張來算
第1張 可衝卷 衝過次數 成功機率 機率
10% 9 0 60% 0.003%
10% 9 1 60% 0.035%

=============================================================================
是否要衝卷?
假設褐手未衝4000萬 手攻卷一張400萬
7 0 60% 0.16384000%
7 1 60% 1.72032000%
7 2 60% 7.74144000%
7 3 60% 19.35360000%
7 4 60% 29.03040000%
7 5 60% 26.12736000%
7 6 60% 13.06368000%
7 7 60% 2.79936000%
每衝一次的成本是4000+400*7=6800萬
如果價錢如下 而且都賣得掉
+1褐手 2百萬
+2褐手 4百萬
+3褐手 8百萬
+4褐手 2千萬
+5褐手 5千萬
+6褐手 2億
+7褐手 10億
那期望值每次就會是(該價錢*該機率)然後加起來的值 = 7488萬
那這樣不考慮運氣因素 衝卷就是賺錢
只算+5/+6/+7的部份 其實就已經差不多平成本了
有時候你會在市場上看到+9/+6/+4的裝備 就是已經有衝失敗的
價格非常的低 如果拿這來衝卷賣 還是有賺錢的可能~
以上 有需要看看 我只是為了以後我要找文章較方便
