📚 Topic Summary
Probability is all about how likely something is to happen. To understand probability, we need to know some key words. An experiment is an activity with uncertain results, like flipping a coin. An outcome is a possible result of an experiment (e.g., heads or tails). An event is a specific outcome or group of outcomes we're interested in (e.g., getting an even number when rolling a die). The sample space is the set of all possible outcomes for an experiment.

✍️ Part B: Fill in the Blanks
Complete the following paragraph using the correct vocabulary words:
Rolling a six-sided die is an ____________. Each number (1, 2, 3, 4, 5, or 6) is a possible __________. If we want to know the probability of rolling an even number, that is the __________. The __________ is {1, 2, 3, 4, 5, 6}.
Answer Key:
Rolling a six-sided die is an experiment. Each number (1, 2, 3, 4, 5, or 6) is a possible outcome. If we want to know the probability of rolling an even number, that is the event. The sample space is {1, 2, 3, 4, 5, 6}.
🤔 Part C: Critical Thinking
Give an example of a real-world experiment, and explain the sample space, a possible outcome, and a possible event related to that experiment.
