"My favorite real numbers are pi, e, and ln 2. The numbers have to be represented with infinite number of digits."

Would that be all right to say?
As SD said, it's all fine. I'm sorry about my suspicion. I simply cannot understand where the problem is. "A" means one. 2 is one real number. Therefore 2 is a real number. The same goes for any other single real number. There really is nothing to it.

For example, there is this sentence from wikipedia:

"In probability theory and statistics, the Poisson distribution ... is a discrete probability distribution that expresses the probability of a...."

Why do they use the? Would it be all right to say

"In probability theory and statistics, a Poisson distribution ... is a discrete probability distribution that expresses the probability of a...."
Yes, it would be fine. By using "a", you would stress the fact that there are many Poisson distributions, one for every lambda. I don't think there's a reason to do this in this context though.

Really? This from the man who wrote, "A distribution is a function. A function is a procedure for computing something from something else. In this particualr case you feed in intereger values to such function and get out values from zero to one (probabilities). Multivariate function is a product of such functions. The real problem is elswehere. It is about whether to treat a set of functions as countable or uncountable".

Are you really surprised that one or two of us are becoming just a trifle suspicious?

Once more, I am really, really, sorry that you have these problem with double identity folks (I have no clue what is going on, and what they have done) but it made some of you paranoid. I am harmless and trying to imrove my English. That is all.

p.s. The reason why I tried to expliain what a distribution is that somebody asked, not to provoke in any way. I am not into numbers. I am into language about numbers if you wish.

Wondeful! This was valuable. Another question, please bear with me, what is that one stresses in the context of the wikipedia sentence when "the" is used?

True, but if you tried asking the question there you might get an answer from people who know. If you don't ask, you won't.

But this would imply that i could write it without any article. Actually, I just realized you did write it without any article. In such a case it would be like a generic concept, right?

You've read the wikipedia article, which contains the sentence: A classic example of Poisson distribution is the nuclear decay of atoms.
