Homework for 4.2 part 2 - The Multiplication Rule 1. In order for the string quartet to play, all four players must show up. The chance that the first violinist will show up is 90%. The chance that the second violinist will show up is 70%. The chance that the violist will show up is 80%, and the chance that the cellist will show up is 60%. They show up - or not - independently of each other. Find the chance that they all show up. 2. Suppose you are tossing a fair coin - a coin with P(heads) = .5. For each pair of options below, say which has the bigger chance - or if the two chances are the same. You should be able to answer without finding the actual chances. But you can check your answers by finding the chances. a. Either you toss the coin 5 times and get heads every time or you toss the coin 6 times and get heads every time. b. Either you toss the coin twice and get exactly one head or you toss the coin twice and get at least one head.

### 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.
