I'm a teacher with study hall 1st period & 3 games in my closet-polled the students to see who would play which game. (The problem on my paper gives names, but I'm just giving numbers.) 5 kids said they would play all 3 games. 5 others said they wouldn't play any games. 3 said they would play checkers & backgammon- 2 said they'd play backgammon & chess-1 would play chess & checkers. This gave the teacher 21 students who would play backgammon or chess, 24 who would play checkers or chess, & 26 who would play checkers or backgammon. How many students wanted to play only backgammon?Only checkers?Only chess? How many were in the study hall?
This is study hall? Times have changed.
yeah, they're no longer allowed to sleep - actually, it must be a non-tenured teacher trying to keep the job- either way, the teacher's just trying to survive - can you help?
If you have names, put them on a spreadsheet, names down, games across in columns.
You can answer each question by counting.
I'd use a venn diagram. Simple, yet effective.
i don't have enough names to make those numbers work, but thanks
