答案:結果是只可能大家一起死。無論怎麼拿1號都是死的,所以怎麼樣他都得拖人下水,1號會拿20個,結果是前4個都拿20個,最後一個拿幾個都一樣,大家一起死。

err

no.2? cos he can counts how many no1 took from the bag....only a quick guess

sorry forgot explain

if no1 took 50, the bag left 50, then no 2 takes 25 the must be in between, if no1 took 30, bag the bag left 70, take 29...etc,
da answer is NO.5 coz he don't hv to do anything n da first 4 people is die already...................
Don't kow
they will all die becuz they will each get 20
真係好難
>:D< 開估啦 !
NO.1 ,NO3 AND NO4
有难度,慢慢想
why
好好想想!
I had a quick guess, is No.1. 4 |( L. n, e% H  ?$ ?1 R0 K
Because what ever he or she taken, the next person will take what ever had taken with +1 or -1 to ensure they havn't got the same number. at the end, no1 will had the most likely middle number and without a same number. of coz he will need to pick a number from 3 to 19.
i don't know
看来我的智商确实比较低,乖乖的等答案吧! :'(
