Probability & Test Corrections

LARGE GROUP
Today students received their quizzes back from last week, and we went over corrections to the problems. Then we talked about two games of chance, Match/No Match and Red & Blue Wins! We reviewed experimental probability and theoretical probability, and making tree diagrams and ordered lists for calculating theoretical probability. Students worked on Problem 1.2, Red & Blue Wins, which you can download here, and figured out whether the game was fair, what the chances were for winning, and how much the school would earn. Class notes may be downloaded here for class 7A or class 7B.

Due tomorrow, Tuesday, June 8.

SMALL GROUPS
MaryBeth met with the small groups for the last time today. Students went over their quizzes on linear relationships and made corrections. Then they discussed probability, including experimental and theoretical probability, and reviewed tree diagrams and organized lists.

SMALL GROUP HOMEWORK
Please complete Problem 1.1, which you can download here.
