Again, the method is good but you misunderstood the puzzle. E( 0, n ) is not n.

Why can't both reach 0? Did you read the puzzle carefully? A simple MC will prove the number should be around 1.4, not 35 / 16, which hugely underestimate the prob for 0 jb left and in turn increased the expectation.

MCarrira, your solution should be right if you not times 1/2 directly but considering the special case which both reach empty state.

<t>Assume you have K beans left, then you have picked totally x = ( n - k ) + n + 1 times. so you need to get the prob for toss a coin x times, get exact n heads( tails ) for first x - 1 try and get heads( tails ) again in last toss. Rember k = 0 will be a special case, where the last toss could be ...

How do you guarantee your 21 ways are equally likely? The answer may happen to be right, although unlikely.

<t>Hiring manager told me today the chance to get approval is higher than 90%. I guess I will believe him. The offer is in FICC, credit structuring. Atreides, is the person you talked hold the same position in this specific group? I feel that they are currently only talking with me from their interv...

<t>Thank you all, dear friends! My situation in detail: I had two verbal offers, first one is in NY, they are trying to apply H1-B for me quickly, but not promise they can get it done in time;second one is in London, I prefer the second one.

Thank you!

<t>Hiring manager told me that they can not give me the formal offer letter until they have discussion in next week's hiring managers meeting. I know it is kind of standard procedure. Is there any risk for my offer?I have another offer which is pushing me to accept due to the visa issue in USA.Thank...

Not yet. I know HH will get money from company. But company may cut my salary due to that, I heard. Though I do not care that one time thing too much. But just want to know what is about fair.

That was the question I asked here before. I do not know the level. But was told by a friend wokring for GS that, for Ph.D, I should get the associate level.I think they even will not discuss any details of the offer with me but with my HH. I feel a little worried.

Sorry, I forget to mention more details. I am fresh Phd. The role is in FICC.

The offer is going to be a front office role in GS in London. What all the compensation should I expect? No one discuss with me about that. I do not know how much my HH will take. Just want to have a rough idea to know what is about fair.Thank you very mcuh!

I have Ph. D degree and the HH gave me a posision in a top IB as a quant ANALYST, is that a mistake? I thought Ph.D should start as Associate, right? I have almost done the interviews.

Thank you very much!
