The probability for the random variable to fall within a particular region is given by the integral of this variables density over the region.

Edited: To answer your question asked in a comment below: Reason (a You said so: " 0 x,." What else is that supposed to mean?
Recall that we can do that by integrating the joint.d.f.
Further details Unlike a probability, a probability density function can take on values greater than one; for example, the uniform distribution on the interval 0, has probability density f ( x ) 2 for 0 x and f ( x ) 0 elsewhere.
Chapters 7 to 9 are about continuous variables.The conditional variance of, y given, x x is defined as: y-E(Yx)2 h(yx)dy) or, alternatively, using the usual shortcut: y2h(yx)dyright-mu2_Yx) Although the conditional.d.f., mean, and variance of X, given that Y y, is not given, their definitions follow directly from those above with the.Help About Wikipedia Community portal Recent changes Contact page.Employed in computing the possibilities of continuous hit-or-miss specifics.Let's take a look at an example involving continuous random variables.It also offers study tools and dictionary and thesaurus entries from Merriam-Webster.In some cases the latter integral is computed much more easily than the former.
