To begin our lesson on probability, let's start with a fun activity. As adults, we often forget the joy of playing games and how they can teach us important concepts. Grab a pair of dice, and let's start rolling!

Roll the dice ten times and record the results. How many times did you roll a 1, 2, 3, etc.? Take a moment to compare your results with a partner.

Now, let's use this activity to introduce the concept of probability. When we roll a dice, there are six possible outcomes - 1, 2, 3, 4, 5, or 6. Each outcome has an equal chance of occurring, making the probability of rolling any number 1/6.

Probability is the branch of mathematics that studies the chance of events occurring. It helps us understand how likely something is to happen and helps us make informed decisions.

In real life, we encounter probability in many situations. For example, when we plan a trip, we consider the probability of rain. When we invest money, we assess the probability of earning a profit.

Before we dive deeper into probability, let's review some of the essential terms we'll be using throughout the lesson:

**Event**: An event is an outcome of a situation, such as rolling a dice or flipping a coin.**Experiment**: An experiment is a procedure that generates a set of events.**Probability**: Probability is the likelihood or chance of an event occurring. It's expressed as a number between 0 and 1.**Trial**: A trial is a single experiment or occurrence of an event.**Sample Space**: A sample space is the set of all possible outcomes of an experiment.**Random Variable**: A random variable is a numerical characteristic that describes the outcome of an experiment.

Probability plays an essential role in our lives and is a fundamental concept in mathematics. As we continue our journey in this subject, we'll learn how to calculate probabilities and apply them to real-world situations. So, let's roll up our sleeves and get ready to work with numbers!
