Probability Quiz Tomorrow!

Tomorrow we will start class with a chapter 14 (math) quiz! Tonight--STUDY!

• The best way to study probability is to do lots of practice problems!
• First, complete 6 multiple choice questions provided in class (or below); the answers are also provided
• Want more practice? Complete "Quiz C" below and check your answers! (also provided)

After our quiz tomorrow we'll get into some new stuff (chapter 15), and start looking at how we can work with events that are not disjoint. Then, on Friday, we'll start class with our chapter 14 vocab quiz and then get back to chapter 15 stuff.

Today's Class Recap:

• Stamp = Math Practice
• Discussed/took notes on probability notation and formulas
• Used the stamp context to show how this type of notation could be used
• Worked in groups on the following (challenging) question:
• Suppose that 37% of registered voters in a certain city are democrats.
• If we survey four voters, what is the probability that at least 3 are democrats?
