**You have a rare opportunity (for our class)--you can re-take a different version of the probability "math quiz!" **

  • However, your re-take score will replace your first score even if it's a lower score...
  • ...so don't just show up and wing the retake! You must study and come prepared--re-do the quiz you got back today!
  • You must re-take the second version by 2:10 on Friday, during lunch, study hall, before school, or after school (Weds/Thurs).

Monday's Homework:

Page 362-365: 4, 9, 11, 17
  • #9 is only in orange because it wasn't listed in the weekend post, the other three were
  • For #9 and #17 you need to know how a deck of cards is made up...here you go:
  • Standard Deck of Cards;
    • 52 total cards
    • 26 red cards
      • 13 red cards are "hearts"
      • 13 red cards are "diamonds"
    • 26 black cards
      • 13 black cards are "spades"
      • 13 black cards are "clubs"
    • Each of the suits (spades, clubs, hearts, diamonds) has 13 cards...
      • 2, 3, 4, 5, 6, 7, 8, 9
      • Jack, Queen, King, Ace
    • So, there are four two's in a deck--a 2 of hearts, 2 of diamonds, 2 of spades, 2 of clubs
    • There are four three's in a deck--3 of hearts, 3 of diamonds, 3 of spades, 3 of clubs
    • Etc...
  • #4 Answer Key:
    • 4a.) 0.14
    • 4b.) 0.23
    • 4c.) 0.77
Today's Class Recap:

  • Stamp = working without replacement (like #19 from the weekend homework)
    • We then went over this problem (about marbles) in our notes
  • HW Questions: Ind, Disjoint MC and book problems
    • Independent/Disjoint MC Answer Key:
      • 1.) E
      • 2.) C
      • 3.) E
      • 4.) B
      • 5.) A
      • 6.) A
      • 7.) C
      • 8.) B
      • 9.) C
      • 10.) A
      • 11.) A
      • 12.) C
      • 13.) B
  • Then we started our next note slide and began a discussion of conditional probability (to be continued tomorrow)...
