36-217 Probability Theory And Random Processes Homework

36-217: Probability Theory and Random ProcessesCourse DescriptionThe theory of probability and random processes provides the mathematical tools needed to model uncertainty in virtually all scientiFc areas. Nowadays, probabilistic models are key for the development and analysis of scientiFc theories and of many algorithms, with countless applications, including the analysis of network dynamics of circuit failure rates, the development of algorithms for computer vision, machine learning, image processing, cryptography, system performance assessment, business inventory, marketing, Fnance, medicine, etc.This is a Frst course in probability theory that is designed to prepare you to develop and analyze basic probabilistic models for describing and studying uncertain or random phenomena and to make better predictions and decisions. By the end of this course, you will1.Possess an adequate background and understanding of basic concepts in probability theory;2.Be able to apply probability terminology and formalism correctly to represent elementary random experiments and quantify uncertainty;3.Be proFcient in the calculus-based mathematical skills needed to solve problems in basic probability.Course Objectives1.Basic Probability.•Describe the sample space of an experiment using set notation.•±ind the probabilities of complements, unions, and intersections of events.•Use counting tools to enumerate the number of equally likely outcomes of simple experiments.•Use the law of total probability and Bayes’ Rule to calculate probabilities.•DeFne and identify independence of events.•Calculate conditional probabilities of events.2.Random Variables•Describe the random variable associated with a question of interest.•Describe and identify discrete and continuous random variables.
