assume number 1, 2, 3 and 4, pick number a, b, c and d.+ ^4 p! h( ~. W; o4 a; r+ R- i
number 4 knows how many left in the bag which is 100-a-b-c

and number 4 can squeeze himself into the average and what number 5 picks.

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.
4 o- E6 Y+ |/ V0 ]tvb now,tvbnow,bttvb公仔箱論壇9 F/ d8 S2 q! X+ y/ c4 C! Y9 i
Starting 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.  " c7 j' u+ B) q! _% i, @( k8 X+ Q

Now #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.

#4 base on knowing the median rule take 60 divided by 3 =20, so he picked 20 as well.

我猜NO4,TVBNOW 含有熱門話題,最新最快電視,軟體,遊戲,電影,動漫及日常生活及興趣交流等資訊。: z/ R' L3 J' m. f% r* s0 v
因為他可以取前面三位豆子的平均數,
& e  Z! u+ n6 `& d5 s. X- M/ Ltvb now,tvbnow,bttvb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: _! Z! S6 x6 n' y: W! g5 j3 ~
