Thursday = STUDY! (Quiz Tomorrow)

Chapter 14 Quiz Tomorrow!

• 2 sections....
• Math Section: 8 problems that are very similar to those on your take home quiz! Use that to study!
• Look over your take home quiz
• Look over/be sure you can do last night's MC homework!
• If you want more practice try the following....
• If you do these I'll count is as an extra credit homework!
• Page 341: 20abc, 28, 30, 32, 34
• Feel free to send me a Remind message if you get stuck!
• Answers are provided below so you can check....
• Also be sure that you know how to do an "exactly 1" problem
• Here's a practice problem you can try--you need to do this for the extra credit too...
• Suppose you are playing roullette; the probability that a spin lands on red is 0.474, the probability a spin lands on black is 0.474, and the probability a spin lands on green is 0.052
• If the wheel is spun 8 times, what is the probability that exactly one spin lands on green?
• Answer = 0.2863

• Vocab Section: here's the vocab list for tomorrow's quiz...
• Probability
• Independent (Events)
• Disjoint/Mutually Exclusive (Events)
• Law of Large Numbers
• Law of Averages
• Equally Likely
• Union 
• Intersection 
• Sample Space
• Complement
• Sum of probabilities of all possible outcomes = 1
