The set of all possible outcomes is known as __________.

Correct option is C

​$$\begin{aligned}&\textbf{1.} \ \text{The \textit{sample space}, denoted by } S \text{ or } \Omega, \text{ is the set of all possible outcomes of a random experiment.} \\&\quad \bullet \ \text{Example: Tossing a coin } \rightarrow S = \{\text{Heads}, \text{Tails}\} \\&\quad \bullet \ \text{Rolling a die } \rightarrow S = \{1, 2, 3, 4, 5, 6\} \\\\&\textbf{2.} \ \text{Each individual outcome in the sample space is called a \textit{sample point}.} \\\\&\textbf{3.} \ \text{An \textit{event} is a \textit{subset} of the sample space.} \\\\&\textbf{4.} \ \text{If all outcomes in } S \text{ are equally likely, it's called a \textit{uniform sample space}.} \\\\&\textbf{5.} \ \text{In probability theory:} \\&P(E) = \frac{\text{Number of favorable outcomes}}{\text{Total outcomes in sample space}} \\\\&\textbf{6.} \ \text{Used in statistics, probability, and random process modeling — critical in \textbf{engineering reliability}, \textbf{risk analysis}, \textbf{simulation}, etc.}\end{aligned}$$​​
