A random variable has the following probability distribution

WebWhen asked to derive the distribution of a random variable it's customary to present the cumulative distribution function (cdf), commonly denoted F Y ( x) := P ( Y ≤ x), for r.v. Y. In your case, it is probably helpful to note that P ( Y ≤ x) = 1 − P ( Y > x). WebDiscrete random variables can only take on a finite number of values. For example, the outcome of rolling a die is a discrete random variable, as it can only land on one of six … bolt action spielmatte
