A question regarding conditional entropy

m...@privacy.net (Lionel B) — Thu, 02 Oct 2008 11:55:33 UT

Given any 3 jointly distributed random variables X,Y,Z, intuition tells
me that H(Y|X) = 0 should imply that H(Z|Y,X) = H(Z|X).
My intuition works this way: since given X there is no uncertainty about
Y, Y should not resolve any uncertainty about Z over and above that
already resolved by X.
I have not managed to prove this... is it in fact true, or is there a

book question

Hi there,
Does anyone have any recommendations for books that would be good
for learning basic and intermediate probability? A mix of theory
and
applications would be great (e.g., a proof of the law of large
numbers
is great, but some real world applications would also be helpful).
Thanks for any advice,

how to generate random numbers that respect a seed condition

Hello
My name is Sara Ferrari, i'm an italian student and i'm starting to use
Matlab and Simulink.
The problem to solve is to generate a serie of numbers that must respect the
follow condition:
the numbers are 9 from 1 to 9
The random serie is long 9^11
every subserie (of 9 numbers)can't have the follow disposition:

Hi. Sorry: I do not know what to call you as you have not signed your

You are indeed confusing three different things.

You have said it is a fair coin. So by definition the chance should
be 50% every time.
Your Bayesian analysis would produce the same result, provided that
before the execise started you were absolutely certain that you had a
fair coin (known as a point prior). If however you had been prepared
to entertain some doubt then the chance that next flip would be heads

Fair Coin Toss?

nstyr...@gmail.com — Mon, 15 Sep 2008 05:19:05 UT

Assuming we flip a fair coin 9 times and get 9 heads. What's the
probability that the coin will come up heads on the next toss?
I'm a li'l confused here. They say a fair coin toss is independent of
other toss, and so the probability should be 50/50. But per Bayes
theorem, we need to revise the probability and that means there's 9/10

Problem: Consider a car owner who has an 80% chance of no accidents in
a year, a 20% chance of being in a single accident in a year, and no
chance of being in more than one accidentin a year. For simplicity,
assume that there is a 50% probability that after the accident the car
will need repairs costing 500, a 40% probability that the repairs will

If the OP does not care about the distribution (e.g. that it be
uniform on the intersection of the hyperplane and the n-cube),except
that the points must be able to lie anywhere in [0, L], then can he
not just sample uniformly from the n-cube, and then project to the
hyperplane in some way? For example, if the sum of the sample is less
