Introduction
You might have students toss number cubes a few times as a real-life experiment as they respond to this headline story.
Headline Story
Alisha and Yuri are playing a game with two number cubes. Alisha gets a point if the product of the two numbers is even, while Yuri gets a point if the product is odd. They each have 2 points so far, but their friend, says the game is not fair. What do you say?
Possible student responses
- They’ve each won 2 rounds, so it seems fair.
- Playing more rounds might make the game seem more fair or less fair.
- Making a table of all the possible outcomes form tossing two number cubes shows that there are 36 possibilities. But, since only 9 of the products are odd, Alisha has a much better chance of winning the game than Yuri does.
