  1. Algebra II—day one • Seating • Expectations • Extra credit if signed by Thursday • On-line books • Who doesn’t have a computer • Book list • Create an account • On-line tutorials • On-line homework quizzes • Moodle • Essential Questions • Homework list • Posted notes • Posted lessons • Create a Google Docs account • At times there may be some links posted for class and you will need a log in, this must be done at home.

  2. Chapter 0Prob, Stat and 4-site testing Where are probability and statistics found?

  3. Statistics --day 2 • How much do you remember about statistics?

  4. Greed Game • Play two games of greed, five rounds each • After game one, find the mean, median, mode, a dot plot, use the sticky notes to do a stem and leaf plot. • After game two create a box plot, then use game one’s stem plot to create a second box plot and compare the center, shape and spread of the box plots

  5. Probability—day 3 • How is probability calculated?

  6. Basic definitionprobability = number of “correct responses” number of trialsprobability can be at most 1 but not less than 0

  7. Examples: • Suppose we draw a card from a standard deck, what is the probability of drawing : • An ace? • A heart? • A red card?

  8. Examples: • There are 5 red, 4 blue and 3 green marbles in a bag. One is selected at random. What is the probability of getting • A blue one? • A purple one?

  9. Geometric example: • A 30” x 40” rectangular cork board has 20 circles with a radius of 2” attached to it. The circles are evenly distributed among 4 different colors: red, yellow, green and blue. If Jim throws a dart at the board and hits the board, what is the probability that he will hit a red circle?

  10. Reminder: • Punnett Square—may have used this in science class in elementary school or middle school • Set up like this • Father on top • Mother on the side • Capital letter is dominant • Lower case is recessive • If a capital is in the combination, the dominant trait occurs.

  12. Homework

  13. Probability—day 4Find the sample space: • What do you do when the total number of outcomes is described but not specified?

  14. Counting Theorem • There are three books to be arranged on a shelf: math, history, and English. How many ways can this be done? • M H E M E H • H M E H E M • E M H E H M 3 •2•1 = 6 ways

  15. Example: What is the probability of getting a total of 5 when a pair of dice is rolled?

  16. Example: • Sue is going to the mall with her friends. How many outfits could she wear if she has five pair of jeans, 10 shirts and 4 pair of shoes?

  17. Permutations: • When order matters: n= total number of items r = number chosen

  18. Example: How many ways can 4 different books be organized on a shelf? How many ways can 2 of the 4 books be organized?

  19. Combinations: • When order DOES NOT matters: n= total number of items r = number chosen

  20. Example: How many ways can 4 books be placed on a shelf without regard to order? How many ways can 3 of the 4 books be placed on the shelf without regard to order?

  22. Homework

  23. Day 5 • Review homework • Do the following sample PSSA problems

  24. Sample related 4-site/PSSA: • Brad is an unskilled dart player. Assume that his throws are a random event. Brad throws a single dart at the board shown in the diagram below and hits the board. Determine the probability that the dart hits the outer ring.

  25. Sample related 4-site/PSSA: • Sam would like to order lunch from Jerry’s Sub Shop. They have 4 types of rolls, 10 toppings and 8 types of meat. • If Sam wants a sandwich with an Italian roll, 4 toppings and any two types of meat, how many different combinations are possible?

  26. Homework Both PSSA problems are due tomorrow!
