  1. Betting on red

    Interesting puzzle. I'm getting some non-intuitive results...
  2. Comparing gambling systems

    Thanks for the code. I think I see what is causing the discrepancy between the simulation results. I made a mistake in transcribing the game probabilities...
  3. Comparing gambling systems

    Excellent insight, bonanova. The idea of using log is brilliant. However, my coding (and theoretical results) disagree with the simulation shown you and prime. winning.pdf

  5. The Best Performer

    I like your answer. It is interesting how in America this problem is solved differently from my home country. I'm intrigued. How do people from your country solve this problem?

    How many days does each person contribute to the total project days? Individuals don't contribute to the project's time. A can do a project, alone, in a days, but a does not increase the time of a project. Rather, 1/a contributes to the reciprocal of the project's time. 1/a +1/b+1/c = 1/10, etc. Allow me to rephrase cause I disagree: Including someone on a project and excluding someone else directly affects the amount of days a project takes. So in terms of making a three man team we can determine the day load attributed to each person (as well as rank them by productivity). In terms of proportional pay for effectiveness this is very important as we in manufacturing projects pay individuals incentives based on their individual contribution to group projects. So, by your later question, are you asking for how long each individual would take to complete the project working on his/her own? [edit from here] This would then, of course, make that proportional payment easier, using [actual time]/[individual time] to determine the proportion of total payment each individual should receive. essentially, i am asking how much of the duration is caused by each individual on the three man team if we assume that a person is just as productive no matter who they work with Let a, b, c, and d stand for the fraction of a project that A, B, C, and D can do within each day, respectively.

    Correct. The star awaits the formula. Recursive formula

    Here's my answer
  9. Whether to switch

    I think I see where we agree and where we diverge now. This two-envelope paradox has two variants, A) There are two envelopes, both of which are unopened. We reach the same conclusion on this one. B) One of the envelope is opened and has $1000. This is where we disagree
  10. Whether to switch

    Can you clarify the part highlighted in red? Do you mean specifically to generate N random numbers from the uniform distribution between, say, 0 and L? If I'm writing code for this experiment, I can't generate a random number without telling the computer precisely which probability distribution to use (and the corresponding distribution parameters). Most computer programs, for instance, will allow one to generate a random number uniformly between [0, L], but then you will need to supply the value for the upper limit L. (Reverend Bayes, is that you?) Randomness comes in many forms (e.g., normal, uniform, exponential, etc. ) and I don't think it is possible to generate random numbers without specifying which probability distribution we are working with.
  11. Division of a Will

    If we want to maximize the minimum perceived percentage plus making sure that no one thinks someone else is receiving more money, then here's an approximate strategy
  12. Whether to switch

    I'd love to hear about this experiment that does not depend on the probability distribution of how much money is in A and B. My feeling is that Reverends Bayes is hiding somewhere, possibly heavily disguised, in the set-up. But I may be wrong, I often am.
  13. Division of a Will

    Can you elaborate on the bolded part? I'm not sure that I can parse that correctly. There are many ways to determine a 'best' answer in this question. Both you and Pickett found effective answer and there are in fact more answers that would work in providing everyone at least 25% of the fair share of the goods and money. I am now seeking the answer that provides everyone the most profit. I do not want the average percentage of perceived benefit from the will, I want to award the 'best' solution to the one who can give the most to the person who received the least. For example: (I am making these percentages up by the way) Remember each person expects to receive 1/4 of the value of the old man's wealth strategy 1's allocation strategy gave the following outcomes person 1=27% person 2=36% person 3=40% person 4=30% strategy 2's allocation strategy gave the following outcomes person 1= 30% person 2= 29% person 3= 28% person 4= 29% though the average gain in strategy 1 is 33.25% which is higher than strategy 2, person 1 only made 2% more than expected so this strategy is not preferred when compared to strategy 2 since its lowest recipient got 28% of the perceived wealth or 3% more than expected. So in these hypothetical cases, solution number 2 is perceived as better since the minimum beneficiary is better than the other cases minimum beneficiary. **and of course these percentages are perceived percentages of value they placed on the old man's wealth. If you are trying to maximize the minimum perceived percentage of the value, then you can divide the property in the following manner
