M302 4/4/08 - Notes The probability of an event is written as “P(the event)”. 1. P(an event) = number of favorable outcomes / total number of outcomes 2. Odds In favor of an event = number of favorable outcomes / number of unfavorable outcomes 3. Odds against an event = number of unfavorable outcomes / number of favorable outcomes Problem 3, pg 731 A) P(Spinner lands on red) = 3 fav / 6 total = ½ B) P(Spinner lands on Yellow) = 2/6 = 1/3 C) P(Spinner lands on Blue) = 1/6 Problem 9, pg 730 Number of favorable outcomes = Number of tickets that Don bought = 6. Number of unfavorable outcomes = 51 total tickets – 6 that Don bought = 45 Odds against Don winning the iPod = 45 unfavorable outcomes / 6 favorable outcomes = 15/2 or 15:2 Chapter11 is about counting the number of options. We learned tree diagrams, product tables, slots, & combinations! In chapter 12, we will be finding mostly probabilities and a tiny bit of odds, BUT we have to be experts at Ch.11 to do the harder problems in Ch.12.

### 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.
