Guided Notes: Probability and Simulation XIName___________________________________AP StatisticsPeriod___________________ AUTHOR \* MERGEFORMAT Mr. Daniels – DOCPROPERTY "Category" \* MERGEFORMAT Probability and RandomnessDate__________________Students will be able to: Math TalkReview:DO NOT USE A CALCULATOR. USE MENTAL MATH.While configuring, THINK of the steps that you must perform to solve them.Be sure to keep quiet and allow others to think.If you’re done, think about MULTIPLE ways to solve this problem. Remember, there is usually more than one.Show a thumb if you have one way to solve the problem, a second finger if you have two ways to solve the problem, etc.Mr. Little has an extensive R&B music collection. He owns 85 of Sade’s songs that represent 20% of his TOTAL R&B music collection. Use mental math to determine the total number of songs in Mr. Little’s R&B music collection.What else can you infer from this challenge? Do NowOne drawer contains 2 blue socks and 7 purple socks. A second drawer contains 3 blue socks and 2 purple socks. A sock is chosen at random from each drawer. Create a tree diagram and respond to the prompts below. What is the probability of getting two blue socks?What is the probability of getting purple at least once?What is the probability of getting two socks that are the same color?Tree Diagram:Ice Cream Patterns!Jody has four bottles of soft drink – one bottle of cola, one of root beer, one of ginger ale, and one of orange. She chooses three of these bottles to take to a party. If she chooses the ginger ale FIRST, what is the probability:She also chooses root beer?She also chooses root beer and cola? She DOES NOT choose an orange pop as her second choice.What else can you infer from your tree diagram? III. WorkspaceIV. Exit Ticket: The World Series (10 points)Using the Balls in a Bag prompt from III, respond to the prompt: If a third ball is removed and placed to the side, what is the probability that AT LEAST two balls are the same color? USE A TREE DIAGRAM. ................
