In probability theory, a probability density function (PDF), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would equal that sample.Dec 05, 2009 YOUTUBE CHANNEL at EXAMSOLUTIONS WEBSITE at where you will have access to all playlists cumulative distribution function worked examples

This section covers Discrete Random Variables, probability distribution, Cumulative Distribution Function and Probability Density Function. A probability distribution is a table of values showing the probabilities of various outcomes of an experiment. . For example, if a coin is tossed three times, the number of heads obtained can be 0, 1, 2 or 3.

Printerfriendly version. A continuous random variable takes on an uncountably infinite number of possible values. For a discrete random variable X that takes on a finite or countably infinite number of possible values, we determined P(X x) for all of the possible values of X, and called it the probability mass function ( p. m. f. ). For continuous random variables, as we shall soon see, the The PMF is one way to describe the distribution of a discrete random variable. As we will see later on, PMF cannot be defined for continuous random variables. The cumulative distribution function (CDF) of a random variable is another method to describe the distribution of random variables.**cumulative distribution function worked examples** The Cumulative Distribution Function for a Random Variable \ Each continuous random variable has an associated \ probability density function (pdf) 0B \.
