Connect and share knowledge within a single location that is structured and easy to search. Whether it is depends on whether the image is countable or not. Why does the probability that a continuous random variable takes on a specific value actually equal zero? This is the principle of indifference.

It is often a good way to obtain probabilities in concrete situations, but vpn connection cannot map network drive is not an axiom of probability, and probability distributions can take many other forms. A probability distribution that satisfies the principle of indifference is a uniform distribution; any outcome is equally likely.

You are right that there is no uniform distribution over a countably infinite set. For uncountable sets, on the other hand, there cannot be any distribution, uniform or not, that assigns non-zero probability to uncountably many elements. This can be shown as follows:. Thus, since we can't enumerate the uncountably many elements, there must be an infinite in fact uncountably infinite number of elements in at least one what is dbms and example these classes.

Thus there cannot be such a probability distribution. I'll elaborate on my comment. I claim that the statement "The probability that a continuous random variable takes on a specific value what is meant by random variable equal zero? I'll stick with the definition that a continuous random variable takes values in an uncountable set, or, what is meant by random variable be more precise, that no countable subset has full measure.

It is the one used by Davitenio, and in the intro of this Wikipedia article. Flip a well-balanced coin. Hence, it is continuous. The good notion here would be the notion of non-atomic measure. An atom is a point with positive measure, so a random variable which doesn't take any specific value with positive probability is exactly a random variable whose image measure is non-atomic. This is a tautology. Another definition of "continuous random variable" is a real-valued what is meant by random variable finite-dimensional-vector-space-valued random variable whose image measure has a density with respect to the Lebesgue measure.

Yes, even Wikipedia gives different definitions to the same object. My what does 420 mean in a text on the subject warning: rant : I really, really don't like the use what does not liable mean in court "continuous random variable", and more generally the use of "continuous" in opposition to "discrete". These are the kind of terms which are over-defined, so that you can't always decide what definition the user has in mind.

Even if it is quite bothersome, I prefer the use of "measure what is meant by random variable continuous with respect to the Lebesgue measure", or with some abuse, "absolutely continuous measure", or "measure with a density". With even more abuse, "absolutely continuous random variable". It is not pretty nor rigorous, but at least you know what you are talking about. PS: As for why your proof does not work, Joriki's answer is perfect. I would just add that the formula.

This is what happens when you have well-balanced coins, non-loaded dices, well-mixed card decks, etc. Then, you can reduce a probability problem to a combinatorial problem. This does not hold with full generality. As I mentioned in the comments, a continuous random variable is one where its cumulative distribution function is continuous. This would imply that the domain is uncountable, but the domain being uncountable does not imply that it is a continuous random variable.

I am using the definition given in Statistical Inference by Casella and Berger, which is not a PhD level text, but maybe a Masters level text, i. Therefore, the counterexample given by D. Thomine is a good counterexample to your thoughts. You can have a random variable with an uncountable domain that has nonzero probability for some values.

But, it is not a continuous random variable because the CDF would have a jump at such points, and therefore would not be continuous. This link contains a good self-contained and simple explanation.

Why is the probability that a continuous random variable takes what is meant by random variable specific value zero? Ask Question. Asked 9 years, 11 months ago. Modified 9 years, 1 month ago. Viewed 21k times. Thomine If you want to have total probability 1 or anything finite, for that matteryou need at most countably many points with nonzero mass.

So the word uncountable does matter. WP says the CDF should be not just continuous but "absolutely continuous with respect to the Lebesgue measure;" this seems to requre that T be considered as a subset of the reals whereas continuity could be applied to the rationals without even bringing the reals into the picture.

Another example to consider is when the c. Show 10 more comments. Sorted by: Reset to default. Highest score default Date modified newest first Date created oldest first. Add a comment. Thomine D.
