WitrynaThe following equation describes the relationship among the random variables Y, X, and Z: Y 0.007 + 1.2X +Z Assume that Z and X are independent because events specific to ABC are unrelated to the market return. The expected value of X is ux = 0.085, or 8.5%, and the standard deviation of X is ax = 0.11, or 11%. WitrynaThere can be 2 types of Random variable Discrete and Continuous. Discrete which cannot have decimal value e.g. no. of people, we cannot have 2.5 or 3.5 persons and Continuous can have decimal values e.g. height of person, time, etc..

WitrynaA discrete random variable has a fixed set of possible values with gaps between while a continuous random variable takes all values in an interval of numbers. A discrete random variable takes only negative numbers while a continuous random variable takes both positive and negative numbers. Witryna26 mar 2024 · A random variable is called continuous if its possible values contain a whole interval of numbers. The examples in the table are typical in that discrete random variables typically arise from a counting process, whereas continuous random variables typically arise from a measurement. Key Takeaway
