Unformatted text preview: STAT/MA 416 September 2, 2011 Problem Set 6 Name: 1. Harmonicas. When ordering a new box of harmonicas, let X denote the time until the box arrives, and let Y denote the number of harmonicas that work properly. Is X a continuous or discrete random variable? Why? Is Y a continuous or discrete random variable? Why? 1 2. Choosing a page at random. A student buys a brand new calculus textbook that has 1000 pages, numbered from 1 to 1000, of course. She randomly opens the book to a page and starts to read! Assume that any of the 1000 pages are equally likely to be chosen. Let X be the page number of the chosen page. Thus, X is an integer-valued random variable between 1 and 1000. (a.) Find P ( X = 122). (b.) Find P ( X = 977). (c.) Find P ( X =- 2). (d.) Find P ( X = 1003). (e.) When x is an integer between 1 and 1000, find P ( X = x ). (f.) Find P ( X 3). (g.) Find P ( X 122). (h.) Find P (12 X 17)....
