Discrete Probability and Simulation
COURSE DESCRIPTION 
This course is an introduction to discrete probability focusing on Bernoulli trials and associated distributions. It introduces basic random processes such as the Poisson process, random walk, and Markov chains. The simulation of random variables and random processes is emphasized throughout the course using the software R. Prerequisites In addition to the common requirements, students should have taken an elementary probability or probability and statistics course. Some elementary knowledge of R is also required, but this will be covered during the optional preliminary workshop on computational tools. Faculty Fall 2019
