1. TODAY IN GEOMETRY…  What’s next…concepts covered before Semester Finals!  Learning Goal: You will find the probability for simple events  Independent practice  AT – Ch.5 Test Retakes

2. WHAT’S NEXT… FINALS!!!

3. Finding Outcomes for simple events: EventNumber of outcomes One die1, 2, 3, 4, 5, 6 One coinheads, tails Deck of cardsA,K,Q,J,1-10 (4 of each)

5. FINDING OUTCOMES OF MORE THAN ONE EVENT: EXAMPLE: You have a coin and a 6-sided die. If you flip the coin and roll the die, how many possible outcomes are there? There are a total of 12 OUTCOMES. Flip to a HEAD: H1 H2 H3 H4 H5 H6 Flip to a TAILS: T1 T2 T3 T4 T5 T6

6. FINDING OUTCOMES OF MORE THAN ONE EVENT: EXAMPLE: At football games, a student concession stand sells sandwiches on either wheat or rye bread. The sandwiches come with salami, turkey, or ham, and either chips, a brownie, or fruit. 18 total outcomes

7. 2 3 3

8. EXAMPLE: You are buying a new car. You can either choose a sedan or a hatchback, then choose the colors: black, red green, blue or light blue, then choose the model: GL, SS, or SL. How many total choices of cars do you have?

9. PRACTICE: You want ice cream. You can either choose a sugar or a waffle cone, then choose the flavors: vanilla, chocolate, or strawberry then choose the topping: sprinkles, chocolate syrup, peanuts, or gummy bears. How may total choices of ice cream do you have?

10. EXAMPLE: There are 8 students in the Algebra Club at Central High School. The students want to stand in line for their yearbook picture. How many different ways could the 8 students stand for their picture? There are 8 positions to fill. To fill the first one, there are 8 choices of students. To fill the next position, there are 7 choices. To fill the next position, there are 6 choice…etc…

11. PRACTICE: Jim was given a new smartphone with a 5-digit passcode. The passcode could contain any digit number between 0-9, but each number cannot be repeated. How many different combinations can Jim have for his passcode? There are 5 positions to fill. To fill the first one, there are 10 choices of numbers. To fill the next position, there are 9 choices. To fill the next position, there are 8 choice…etc…
