Detailed Summary
In section 7.2 'Basic Terms', we delve into fundamental concepts in probability that are foundational for understanding how probability works in practice. We start with an experiment, defined as any action that can produce results or outcomes, like tossing a coin. Each time we perform this action, we conduct a trial. The outcome of a trial is one specific result, which could be heads or tails in the case of a coin toss.
We also introduce the concept of sample space (S), which is the complete set of all possible outcomes of an experiment, such as {1, 2, 3, 4, 5, 6} when rolling a die. This leads us to define an event (E), which is a specific subset of the sample space, allowing us to focus on outcomes of interest. An example provided helps solidify these concepts: when rolling a die, the sample space encompasses six values, illustrating how we can organize and analyze possible results efficiently. Understanding these basic terms is pivotal as they serve as the building blocks for more advanced probability concepts discussed in subsequent sections.
