There was a posting on Piano Group Buy a few days ago and I replied to join,
but I have not heard anything. Not sure if it is due to the technical
issue with the website.
Anyway, if the group buy is still on going, please email me l****[email protected]
and I would like to join. if not, I negociated a deal with a dealer during
the weekend. The price for U1 is $5,850 if we have ten people and the
price includes bench, 2 tuning, and 10 year warranty.
Let me know and you can email me at l****[email protected]

想请教一下,如果想买Sprint版的Samsung Galaxy 手机,以后unlock了,可以用在AT&
T,Verizon,或者 T-mobile吗?另外Sprint手机在中国买SIM卡,是在移动还是联通?
本来一直是在AT&T,2年合同已满,不曾想AT&T已不再提供那种手机不到$200的2年合同
,反正手机要全价购买,就想加入sprint的50%off,但对它的网络覆盖和网速不是很有
信心,所以才有上面的疑问,多谢好心人解答。

Of course, you should swap.
there is 1/3 chance that your current holding is Joke, in this case, you
lose if you swap,
there is 2/3 chance that your current holding is NOT joke, in this case,
you win if you swap,
so you should swap.

It should be 1/2 becasue there is one card not joke in dealer hand.
in this case, you
you still have 1/2 chance to get card from dealer's hand by swaping.
1/2 vs 1/2 no meaning.

given i know which one is a not a joker for sure, the probablity of my
card being a joker is 50%, is that right ?
this is what i think.
initially, i pick 1 out of three, my chance of getting a joker is 33%.
the second chance, i know one is not a joker. if i pick, my chance is
50%. if i dont make the pick, i will be staying with the decision i have
made when I only had 33% of chance. I would increase my chance to 50%
by picking it again.

Faint,
if you current holding is not a joke, between the 2 cards left, the dealer
already told you which one was not a joke, so the one left is always joke,
of course you need to swap your holding with that card!

From the player's view, if the player always chooses to swap, on average,

1. strategy one: do not the swap, you win when the first card is a joker, so
the probability is 1/3.
2. strategy two: do the swap, you win when the first card is not a joker(
since the dealer will point out which one is not joker and you get the joker
if the first card is not a joker). So the probability is 1-1/3=2/3
You swap. Basically, if you do not swap you are not using the information
given by the dealer while you do swap you use this information.

No. Think in another way, if there are 1000 cards, one of them is a joker
and after you choose the first card, the dealer will point out the 998 cards
of the remaining 999 cards which are not joker. Do you swap ? According to
your logic it is still 1/2 since you only choose from only two cards(notice
the dealer point out 998 cards). Now if you let the number of cards go to
infinity then, you will find that it is definite a good idea to swap since
the chance you do not get a joker at the first ch

1. 这是一道面试题。已经用了很多年了。
2. 大概10多年前有人问过我,当时吃dinner。
3. 这道题在面试过程中suppose你用最多3分钟时间而且是直接给出答案。当时饭桌上
就是这个要求。我大概是用了一分钟左右,然后他问为什么,我好像说的是三分之几。
他说,其实他就是面试官,很多人这道题都fail了。
4. 现在重新回忆这道题,我还真是忘了一瞬间是怎么想的。现在仔细思考了一下。 这
道题的思路是这样的:
假设三个ball分别为a,b,c的话,结论是根据你做出的对比。
假设你第一次抽的是b, 第二次还剩下a和c,而a和c之间只有一个确定不是,然后假设
a肯定不是 (a和c任何一个被假设都行),那么c是joker的概率是1/3
before swapping, P(b) = 1/3
after swapping P(b') = 1-P(c) = 1-1/3 =2/3
既然2/3 > 1/3, 那你当然应该swap了
avatar

58
补充说明一句:
这道题在面试的时候,suppose你不需要用笔和纸的,因为他给你的只有3个ball。
其实考的就是你的直觉和判断,当时你答对了就是对了,没什么可说的。
这种题,如果做不出来的话,fail的概率大一些。因为后面的面试题要比这个更有挑战
力。
当时他还说了,除了这道题以外,还有的题目就是Texas hold 'em里的一些策略,当然比
这个有灵活度和思考力了。

换不换都一样,
第一种理解,
1. 当Dealer在放屁,死都不换,1/3概率
2. 如果换,两种情况
a. 第一张是joker,P=1/3 * 0=0
b. 第一张不是joker,P=2/3 * 1/2 = 1/3
所以0+1/3 = 1/3
第二种理解,剩下牌中肯定有一张不是joker,Dealer仍然在放屁,所以换不换的概率相
等,因为是两次独立事件。
我的理解,正确么?
