Just Joking !!!
The best chance is #3 because all he needs is take #1 + #2 divide by 2. e.g. #1+#2=28 then he take 14. This is the best chance to avoid being highest or lowest and worst case scenario is he equals #1 & #2. However because all 5 knows this simple theory so I think they all died because they all ended up picking the same number of beans.公仔箱論壇* J- s" f/ F& ?, g' N# ?

7 U2 [: ~, b1 E6 Itvb now,tvbnow,bttvbStarting from #1, he knows he cannot pick anything bigger then 49 because if he did, then #2 only have to leave 3 beans for #3 #4 & #5 then he'll live. e.g. #1 picked 53 then #2 picks 100-53-3=44.  then A,C,D,E all died. e.g. #1=53, #2=(100-53-3)=44, #3=1, #4=1, #5=1. The best chance for #1 is to pick anything less then or equal the median 20 (100 divided by 5). In fact anything between 3-20 won't change the result. Let's say #1 pick 20.  5.39.217.764 `. U3 ^% {. D5 h9 K

% n4 j+ R1 Z6 z/ ]5 t  btvb now,tvbnow,bttvbNow #2 knows whatever he picks, #3 will take the median between him & #1 e.g. now #1 picked 20, if he pick 6 then #3 will pick 13 putting him either being the lowest or highest. He cannot allow that so the best chance is to match #1, so he picked 20 as well.

#3 did the obvious choice 40 divided by 2 =20, so he picked 20

#5 same as above, he takes 80 divided by 4 =20, picked 20 as well.

Ended all have the same number and all died.
我猜NO4,tvb now,tvbnow,bttvb: @0 v$ o) D" t4 U' X9 [9 i0 N  g# E: |
因為他可以取前面三位豆子的平均數,
9 X9 N$ H  V8 s2 [! |: l7 E" x5 S也可以防止豆子不夠讓NO5墊底。
最后一个人最安全!因为当四个人拿完之后,他可以拿quarter of 之前拿的总数,咁样嘅话,佢係最大或者最小的几率係最低嘅```而前面几个人,用呢种方法摞会係最大或者最小的几率会比5号大D...而呢种方法係最有效避免最大或者最小嘅
