Exercise · ZW-SAMPLE-SPACE-005 · ★★☆ Intermediate
Two dice are rolled and only the sum is recorded. How many elements does the sample space have?
Choose one option.
Show answer
- A. 11
Explanation
The possible sums are \(2,3,\dots,12\): 11 values. 36 would be the size if each pair were recorded.
Review the concept: Sample space
A sample space \(\Omega\) is the set of all possible outcomes \(\omega\) of a random experiment.
\[\Omega=\{\omega_1,\omega_2,\omega_3,\dots\}\]
