comment How to approximate the bounding region of a 2d differentiable mapping locally?
Thanks, I used a this package to triangulate the set and apply $f$ on the vertices and then get a Convex Hull of the mapped points. It works ok so far.

comment Asymmetric random walk with unequal step size other than 1.
Still, it is not trivial. I still need to solve high degree polynomials equation for hitting probability. For mean hitting time, it is trivial.

comment Asymmetric random walk with unequal step size other than 1.
the issue is, when $a$ is large, it is not so simple to solve the equations

comment How to solve this inhomogeneous recurrence difference equation?
I updated my question as I am only interested in the positive solutions which are not infinity. So far I can only find one for the example case

comment Can we say that 2 random variables $(X, Y)$ are independent if $P(X \mid Y=y)$ is a function without $y$
@Sasha Hopefully I made it clearer after edit.

@Damieh Multiplier always apply to the final total. Btw, do u know how to make comments friendly for dollar sign?

comment Should I ignore $0$ when do inverse transform sampling?
@André Nicolas: however, in a program, when Random.next() generates values [0,1), if it happens to output 0... the whole program I build upon the sampling algorithm would crash.

comment What's the expected value in this jackpot winning experiment.
i doubt that it has nothing to do with p, i had thought we have to apply some posterior on that. (Bayesian inference) Is it valid that each trial has equal chance to win a jackpot regardless of how low the prior p is?
