comment What's the probability that I will earn \$25?
You can use Markov chains to model this problem. Take a look at: mathpages.com/home/kmath084/kmath084.htm

comment Boy and Girl paradox
@Gerenuk: One picks the uniform probability mass function (pmf) because it maximizes entropy. Thus, if we have no information at all, we assume a uniform pmf over $\Omega$. If you tell me that one of the children is a boy, then one of the points in the sample space is eliminated and the pmf is updated as we assume a uniform pmf over $\Omega'$. This is a Bayesian interpretation of the problem. Would be interesting to think of a Frequentist interpretation.

comment Boy and Girl paradox
@Gerenuk: By "first child" and "second child" I meant "1st child that was born" and "2nd child that was born", i.e., I was referring to chronological order. The order in which you observe them does not change their dates of birth ;-)

comment How to divide currency?
@Auke: Ill-posed problems cannot be answered mathematically, but one can point out why they're ill-posed and try to steer the OP towards well-posed problems. I suggested a cost function at least. You just whine. If you dislike my answer so much, just downvote it.

@Auke: The question was not mathematical either, given the OP's lack of definition of "optimal". Garbage in, garbage out...

comment calculus of variations question
Equation? What equation? I see none. Moreover, what are the limits of integration? You should integrate from $a$ to $b$ so that you obtain a scalar instead of a function, which is what a functional does.
