OBJECTIVE: Use tree diagrams to count outcomes(13-1, Pp492ff) ACTIVITIES:[[DP21 Francine took a math test. She divided by -15.67 instead of multiplying by 15.67. The computation gave the answer of 25. What was the answer she should have given? Write a number sentence!]] From 492: You are given a T-F pop quiz with 3 questions. You don't have a clue. What are your chances of passing by guessing? How would you figure them out - specifically what are the possible OUTCOMES NOTES: OUTCOMES SAMPLE SPACE TREE DIAGRAM HOMEWORK: P493 #3 [Some sample probablity stuff...]
