**Continuous Random Variables Joint PDFs Conditioning**

One Function of Two Random Variables Given two random variables X and Y and a function g(x,y), we form a new random variable Z as Given the joint p.d.f how does one obtain the p.d.f of Z ? Problems of this type are of interest from a practical standpoint. For example, a receiver output signal usually consists of the desired signal buried in noise, and the above formulation in that case reduces... A joint pair of random variables can also be composed of one discrete and one continuous random variable. This gives rise to what is known as a mixed joint probability distribution. This gives rise to what is known as a mixed joint probability distribution.

**self study Determine density of $\min(XY)$ and $\max(X**

To find this probability we simply use the CDF of our random variable. Because the CDF tells us the odd of measuring a value or anything lower than that value, to find the likelihood of measuring between two values, x 1 and x 2 (where x 1 > x 2 ), we simply have to take the value of the CDF at x 1 and subtract from it the value of the CDF at x 2 .... The random variable is said to be the mixing random variable and its pdf is said to be the mixing weight. An equivalent definition of mixture is that the distribution function is a weighted average of a family of distribution functions indexed by a mixing variable.

It can be called the quantile function representation. The quantile function (or inverse distribution function, if you wish) is deﬁned by F−1(y) = inf{x : F(x) ≥ y}. (1) Now it is well known that if U is a Uniform(0,1) random variable, then F−1(U
