**Problem 214 of Prof. Kim's Notes**

Let \( \Omega = \mathbb{R} \) and \( \mathcal{F} \) be the \(\sigma\)-algebra generated by \( A = \mathbb{Q} \) (i.e., \( \mathcal{F} = \sigma(\{\mathbb{Q}\}) \)).

(a) Write explicitly all the sets belonging to \( \mathcal{F} \).

(b) Characterize all the mappings \( X : \Omega \rightarrow \mathbb{R} \) that are random variables with respect to \( (\Omega, \mathcal{F}) \).
