Presentation Transcript

  1. Probability 6.4

  2. Outcomes • Possible results of an action • Examples: • 6 outcomes for rolling a dice (1,2,3,4,56) • 2 outcomes for flipping a coin (heads or tails)

  3. Event • The outcome or group of outcomes

  4. Probability of an Event

  5. Find the probability of rolling one number cube • P(odd number) • P(2) • P(5 or 6)

  6. All Probabilities range from 0 to 1

  7. Classic Probability Problems

  8. Complement • The opposite of that event Example: Rain and No Rain are complements • Probability of Event + Complement=1

  9. When you roll a number cube what is the P(not 2)? • P(2) + P(not 2) =1

  10. What is the complement of an impossible event? • A certain event

  11. Finding Odds ODDs in Favor of an Event ODDs Against an Event

  12. ODDS What are the odds that a quarter chosen at random from the five shows a horse? 1 to 4 What are the odds that it shows no horse? 4 to 1

  13. ODDS Consider the event of randomly choosing a quarter that shows the outline of a state. What are the odds in favor of this event? 2 to 3 What are the odds against the event? 3 to 2
