Yeah the thing is all this optimism is something I took into account. What you didn't take into account is that the coin has a second side, pessimism, if you don't get your fix soon. A habit that gives a high doesn't only give highs, it also gives lows. You probably misunderstood my way of...

I'm in disbelief you actually believe that. Do you seriously think the US government goes into wars in the Middle East for Altruism alone?

Well obviously I'm not talking about mentally challenged people, but if two people are relatively distant in pure IQ tests (given the same initial education on abstract concepts that may aid such a test), will it play any significant role after a point? Will the smarter person ever be able to...

I never understood why people ever believed the propaganda that any country goes into a war with another country to "help its people". When did that ever happen?

Nothing. Human progress will never end so if you have the illusion that you will be happy if you see some innovations you are wrong. If you see alien life you will then wonder if you will meet intelligent life, and if you see a CPU doing 100x the work of those now you will then wonder if one...

Is it normal for university exams to never include some of the material that is in the curriculum? I have some modules that are quite extensive, but about 4 to 5 groups of exercises appear to repeat in the last few years. However, they also ask for students to study about 10 to 15 types of...

A Binomial problem (an extension of a Bernoulli one) is quite clear in dealing with the determination of probability to have a certain number of hits based on a certain number of tries and a particular probability of success of each try. The rest you mention about determining the actual...

I agree. My reasoning was also strengthened by doing a mind exercise where 1,2,..,n boxes were being offered and all but the first box were blocked and only the 1st was left for me to choose. Well, each box entity had from the get go 1/n, why change now?

I had no idea what an identity is but it appears to be one since the relation is formed by combining probability functions that do consider ρ to be distinct for a particular distribution. It also comes to reason they are continuous which might play a role.. Hands up, I realize I could have...

That makes perfect sense. Per the first reply, doesn't continuity play a role?

I suspect the answer lies closer to the first reply. That it's related to continuity.

Are the mods able to see our IP address?

And I'm not convinced it proves it for all. What am I missing? I keep hearing "If I set x and y tending to those numbers ρ must be 0". Yeah, fine, that's obvious. Why does that restrict ρ to one number?

Hence it's insufficient for the needs of the exercise. It was explicitly asked to prove that "only when p=0" that expression can be true.

I don't get this logic. If you find an x and a y that point to ρ = a then how does that prove ρ must always be a? There is something missing in the explanations in text. I'm sure it's possible that's correct but I don't see it when reading the texts here about it.
