  1. Thursday, May 3rd Warm up • Solve: 15=5 - 10x • The letters EVANS PEZZINO were put in a bag. Two letters were chosen without replacement. Find P(vowel, not vowel) Write Down Math Homework Complete warm-up

  2. Attention Attention Checkpoint TOMORROW

  3. Practice Independent & Dependent Events

  4. Tree Diagrams Finding outcomes……

  5. All outcomes are listed on the RIGHT/VERY BOTTOM • A tree diagram is a way to show all of the possible outcomes.

  6. Example #1 I have a photo of Sidney that I want to mat and frame. I can choose from a blue, purple, red, or green mat and a metal or wood frame. Describe all of the ways I could frame this photo with one mat and one frame. You can find all of the possible outcomes by making a tree diagram.

  7. The Tree Diagram • Each “branch” of the tree diagram represents a different way to frame the photo. • The ways shown in the branches could be written as (blue, metal), (blue, wood), (purple, metal), (purple, wood), (red, metal), (red, wood), (green, metal), and (green, wood).

  8. You Try! A baker can make yellow or white cakes with a choice of chocolate, strawberry, or vanilla icing. Describe all of the possible combinations of cakes.

  9. Tree Branch yellow cake white cake vanilla icing vanilla icing chocolate icing chocolate icing strawberry icing strawberry icing The different cake possibilities are (yellow, chocolate), (yellow, strawberry), (yellow, vanilla), (white, chocolate), (white, strawberry), and (white, vanilla).

  10. Method #2 Counting Principle

  11. Example #1 License plates are being produced that have a single letter followed by three digits. All license plates are equally likely. Find the number of possible license plates. Use the Fundamental Counting Principal. second digit letter first digit third digit 26 choices 10 choices 10 choices 10 choices 26 • 10 •10 • 10 = 26,000 The number of possible 1-letter, 3-digit license plates is 26,000.

  12. You try! 1. Employee ID codes at the mall contain 2 letters followed by 3 digits. Find the number of Possible ID Codes.

  13. The Fundamental Counting Principle tells you only the number of outcomes in some experiments, not what the outcomes are. A tree diagram is a way to show all of the possible outcomes.

  14. Classwork Complete Practice A Counting Principals
