  1. I'm late to the party, but basically since I just knew that the density of a sum of N i.i.d. random variables with density p is simply the N-fold convolution of p with itself, I tackled this one with Laplace transforms. You can transform that convolution to the Laplace domain to get 1/(s^N). Next, you do the inverse transform to get the density of the sum on [0,1] as q(x) = x^(N-1)/(N-1)!. Now choose alpha in [0,1] and integrate q(x) from 0 to alpha to get P(sum<alpha) = alpha^N/N! Looks like that's what others have as well.
  2. Glad you're doing okay :)

    I'll post again when Monte posts his next problem! ;)

    I've been doing a lot of probability lately so when I saw that last problem I was like oh I know how to do this lol

  3. I pop in every once in a while :)

    How are things?

    And don't worry, we can still party

  4. My solution, though I assumed the formulas for the distributions of min and max of i.i.d. random variables, cuz 2 lazy 2 prove: https://www.dropbox.com/s/7xhmlpaq7xz4dpk/MeanMeanMean.pdf?dl=0
  5. I'm afraid you will find that most here are ignoramuses, quite obtuse, and definitely mathematically illiterate. Excellent post.

  6. Good post. Don't despair, you're not the only one who notices how utterly vapid her posts are most of the time.

  7. honestly, i'll save you the embarrassment. good day.

  8. OK, then what exactly were you trying to point out?

  9. i don't see a contradiction. if im seeing something that isn't there, then your posts don't exist. assuming they are there, because i can see and read them, they do exist, and im not seeing what isn't there.

  10. If you think you see a contradiction, state it clearly. There is a chance you might be seeing something which isn't there, after all, and if that's the case I'm never going to see what you're refering to.

  11. Yes, it is true that the idea of blacks as helpless and wanting to be coddled has an origin in white people. Not just whites who plainly don't like blacks, but also self-hating whites who are slavishly guilt-ridden as well. This isn't to say that blacks themselves aren't partly responsible for their own image, though.
  12. What's your point? The reason I speak mainly with other white people is because I'm more interested in destroying this insidious white guilt complex. The idea that blacks are helpless and need to be coddled by whites because of supposed institutional biases against them is largely perpetuated by idiot whites afflicted with white guilt on account of their "white privilege". If blacks are offended by this, then they should do a better job speaking out against it. That hasn't seemed to happen, though, so one gathers that perhaps blacks, collectively, are helpless and need and want to be coddled by whites. Perceptions are important, and the black community doesn't seem to be doing a good job at dispelling this image, whether it's true or not for a majority of blacks.
  13. Thanks. I just wish that white people in general weren't so stupid/spineless/complacent and would stop perpetuating the whole guilt complex. Ugh.

  14. I admit that I'm used to speaking mainly to white people on this matter. It is actually quite refreshing to hear that this mentality is at least not universal among blacks (not that I expected it to be). Cool. I was just making commentary within the context of the discussion on white guilt, is all. I think we're on the same page.
  15. You make excellent posts about racism. It's so refreshing to see others who get it. I'm so sick of the entitlement attitude.
