Dear Sam,
I'd like to thank you first for your effort of training us. I benefited a lot although I started solving your problems today. I found that my answer of this question is different from your solution. The process is the same, just the final step of calculation is different. Best wishes. Victor (0.51/e)/root of (2/eeEXP2)=0.17 N=square of (2.33/0.17)=187.85. So my answer is N should be at least 188. Quote:

Dear Sam,
Since I am not a native speaker, I was confused by this question. Did they each put one dollar in the pot, or each put $0.5 only. Surely I got the right answer, because there's no answer for the latter understanding. Regards. Victor Quote:

A question for Professor Broverman
Dear Professor Broverman,
I have a question for this problem. When we are trying to find out the value of c, we integrate f(x) over x to get 1. However, should we consider f(0)=c, which is not included in the two parts of the integration (indefinite, 0) and (0, +indefinite)? If yes, the c=1/3 but not 1/2. Thank you in advance. Victor Quote:

The integration could be considered as (infinity, 0] and (0,+infinity) or (infinity,0) and [0,+infinity]. The integrals give the same result either way.

Gandalf,
Thank you for answering the question. victorandjenny, For the Mar 19/07 question, they both start out each putting $1 in the pot. Then more is added by the person who tosses the dice first. For the Apr 21/08 question, it appears that I made an error. I will post a correction. SB

Dear Professor Broverman,
Thank you very much for your clarification. I am suing your manual for SOA P (Actex) and I really like your book. Best wishes. Victor Quote:

may 12/08 question
Dear Professor Broverman,
I was trying to solve this problem and could not find how or why it turned out the way it did. Here is the part that i did not understand. var(E(XY))={2=E(XY=0) prob 1/3 =(24)^2 (1/3)(2/3) = 8/9 {4=E(XY=1) prob 2/3 I do not understand the solution to that part or how it was arrived at. Thank you for any help.

I believe that's the Bernoulli shortcut?
