Simple events

Start by having your students play this game, or this one, or do this activity. They will learn the same thing regardless of which you choose. Then ask some basic questions, such as what is the probability of rolling a number greater than 3 on a standard dice? Here's such a question.

Next, students will learn about repeated independent events. For example, how many times would you expect to roll a number less than \(5,\) if you roll \(34\) times?

a lesson on that, and here's practice. After that, show your students the probability of winning the lottery. Consider your odds when buying \(1\) ticket or \(n\) tickets. Here's a good video for the \(1\) ticket case. Next, give your students this challenge. After that, give them this one. Finally, show them this video.
