<aside> 💡 $S=\{\text{even, odd}\}$ for a number
</aside>
<aside> 💡 $S=\{(H,H),(H,T),(T,H),(T,T)\}$ for two coin flips. Note that both $(H,T)$ and $(T,H)$ are shown so that each outcome is equally likely, but this does not really matter.
</aside>
Every outcome in a sample space
<aside> 💡 $(H,H)$ is a sample point for the above example
