Introduction: Quick Review Objective: To write odds in favor and against an event Vocab: 1.odds in favor of an event= one possible outcome2.odds against an event= set of ALL possible outcomes
Glossary
Guided Instruction:Example 2: Finding the odds in favor/against an event • BOOKKEEPER
• A. Odds in FAVOR of choosing O (favorable 2,
unfavorable 8) =
___/___, _____ to _____, or _____ : ______
• B. Odds AGAINST choosing K or P (unfavorable 7,
favorable 3) =
•___/___, _____ to _____, or _____ : ______
___/___, _____ to _____, or _____ : ______

Introduction: Quick Review Objective: To write odds in favor and against an event Vocab: 1.experimental probability= number of times a favorable outcome actually occurs compared w/ the total number of times you do an activity: experimental probability = number of favorable outcomes that occur/total number of trials
Glossary
Guided Instruction:Example 1: Finding the experimental probability of an event • Green (2), Red (10), Yellow (13)• P (green) = 2/25, .08, 8%• P (red) = 10/25=2/5, .40, 40%• P (yellow) = 13/25, .52, 52%• Theoretical Probability?? Pablo had 10 green __________, 50 red __________, and 40 yellow_____________
RECAP: Match the vocab word with its definition •one possible outcome
•set of ALL possible outcomes
•one possible outcome
•number of times a favorable outcome
actually occurs compared w/ the total number of times you do an activity:
experimental probability = number of favorable outcomes that occur/total number of trials
•set of ALL possible outcomes
•P, number of FAVORABLE to POSSIBLE
results: P (event) = number of favorable outcomes/number of possible outcomes
• outcome
• odds in favor of an event
• sample space
• experimental probability
• theoretical probability
• odds against an event
• I = prt
