comment writing down markov chain transition matrix
Could you please clarify your question? You ask, "How to write down transition matrix?", yet also include a transition matrix in the statement of your question. Are you saying that the reported matrix is correct, but you don't understand why? Or that you think this matrix is incorrect? Or what?

comment Is a subset $B= {(-\infty,t),t\in \mathbb{R} }$ an event of sample space $\mathbb{R}$?
@Zen is correct, and I was mistaken. I have edited my answer accordingly.

comment Measuring representativeness of a (non-random) selection
@Thilo: Oh, dear. I suppose I invited that follow-up, so have only myself to blame. Answering would, alas, take a long while. 'Any' stats textbook will cover the topic: see, e.g., W.H. Greene, Econometric Analysis. On 'why not?', I'll recommend a book I find canonical that covers the philosophical and practical problems of hypothesis testing quite well and in depth: Statistical Decision Theory and Bayesian Analysis by J.O. Berger, amazon.com/gp/product/1441930744. Very short answer: I'm interested in using stats to make better decisions under uncertainty. HT doesn't help.

comment Measuring representativeness of a (non-random) selection
There is a noteworthy economic literature on statistical measurement of race and sex discrimination in, e.g., labor markets, that might be useful. A seminal work is: The Statistical Theory of Racism and Sexism Edmund S. Phelps The American Economic Review Vol. 62, No. 4 (Sep., 1972), pp. 659-661 Published by: American Economic Association Article Stable URL: jstor.org/stable/1806107
