Starting with simple everyday examples, we explain what a random experiment is, such as tossing a coin or rolling a die, and how it leads to different outcomes. You'll then understand what defines an event, how to identify favorable outcomes, and distinguish them from total outcomes. We also explore the idea of equally likely outcomes, a key concept when determining fair chances. Finally, we’ll introduce the fundamental probability formula—favorable outcomes divided by total outcomes—making it crystal clear with real-life applications and interactive visuals.

Some events will always occur. They're call sure events. Some events will never occur. They are called impossible events. At times, we need some basic math skills to figure out whether we're dealing are impossible or sure events.
