PHYSICS 6 SPRING 2006 HOMEWORK 4 (due Thurs. Mar.16) Read: Goldstein’s Notes on Probability (Course Documents) Hoffmann , Chapters 2-8, 11, 13, 14 to p.186. This is to be read over the next two weeks. It covers the historical development of quantum physics. You may choose to read all the chapters - they're interesting. Feynman , Chapter 6 - read for next assignment. Problems: (1 and 2 use some basic concepts in probability. There will be a handout.) 1. Assume you have a single normal six-sided die (one of a pair of dice). (a) What is the probability of getting one 5 in one toss of the die? (b) What is the probability of getting only one 5 in two tosses of the die? (c) What is the probability of getting at least one 5 in two tosses of the die? (d) What is the probability of getting 0 or 1 or 2 or 3 fives in three tosses of the die? (e) What is the probability of getting only one 5 in eight tosses of the die? (f) What is the probability of getting only two fives in eight tosses of the die? 2. It is observed that for 1000 radioactive Iodine(131) atoms an average of 455 undergo decay in

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
