Continuous random variable

A random value that can take any fractional value within specified ranges, as contrasted with a discrete variable.

Continuous Random Variable

A random variable that may take any value within a given range. That is, unlike a discrete variable, a continuous random variable is not necessarily an integer.

In a companion to The Probability Handbook, McShane-Vaughn presents problems corresponding to each of the chapters in the mother volume: learning to count, the rules of the game, discrete probability distribution problems, and continuous probability distributions. She accompanies each probability problem with a detailed numerical solution and an explanation in a conversational style, and where applicable, also presents solutions using Excel.
