Are any two (or n) random variables always jointly distributed in some sense?
When will two RV's be non jointly distributed?

Joint distribution functions can always be defined. In case of independent random variables, the joint distribution is simply the product of the individual distributions.
 
mathman, thanks for the reply.
So if there are two normal random variables, the a bivariate normal distribution is always defined between them?

If I have random variables, each with different distribution, even so it is possible to find a joint distribution between them?

Yes, to both questions.
 

Thread 'Here's a Statistics problem for game of Polo (or Hockey if you like)'

Namaste & G'day Postulate: A strongly-knit team wins on average over a less knit one Fundamentals: - Two teams face off with 4 players each - A polo team consists of players that each have assigned to them a measure of their ability (called a "Handicap" - 10 is highest, -2 lowest) I attempted to measure close-knitness of a team in terms of standard deviation (SD) of handicaps of the players. Failure: It turns out that, more often than, a team with a higher SD wins. In my language, that...

Thread 'Roulette wheel physics and probability'

Hi all, I've been a roulette player for more than 10 years (although I took time off here and there) and it's only now that I'm trying to understand the physics of the game. Basically my strategy in roulette is to divide the wheel roughly into two halves (let's call them A and B). My theory is that in roulette there will invariably be variance. In other words, if A comes up 5 times in a row, B will be due to come up soon. However I have been proven wrong many times, and I have seen some...
