EE 562a: Random Processes in Engineering EE department‚ USC‚ Fall 2014 Instructor: Prof. Salman Avestimehr Homework 1 Solutions 1. (Axioms of Probability) Prove the union bound: n P [∪n Ak ] ≤ k=1 P [Aj ]. j=1 The union bound is useful because it does not require that the events Aj be independent or disjoint. Problem 1 Solution We prove this part by induction‚ for k = 2 we have P (A1 ∪ A2 ) = P (A1 ) + P (A2 ) − P (A1 ∩ A2 ) ≤ P (A1 ) + P (A2 ) (1) Now‚ assume that

I drove a little blue Ford Festiva and had it packed to the point where I didn’t think anything else could fit in it. It was a beautiful sunny morning when we left on our journey

Random number tables have been used in statistics for tasks such as selected random samples. This was much more effective than manually selecting the random samples (with dice‚ cards‚ etc.). Nowadays‚ tables of random numbers have been replaced by computational random number generators. Tables of random numbers have the desired properties no matter how chosen from the table: by row‚ column‚ diagonal or irregularly. The first such table was published by a student of Karl Pearson’s in 1927‚ and

I. Introduction Arrowmark Vending has the contract to supply pizza at football games for a university. The operations manager‚ Tom Kealey‚ faces the challenge of determining how many pizzas to make available at the games. We have been provided with demand distributions for pizza based on past experience and know that Tom will only supply plain cheese and pepperoni and cheese combo pizzas. We also know that there is a fixed cost of $1‚000 allocated equally between the two types of pizzas‚ and that
