**Mathematics Exercise: Understanding Set Theory**

1. **Given Sets \(D, E, \text{and } F\) Defined:**

   Where \(\mathbb{R}\) represents the set of real numbers. (6 points)

   - \(D = \{x \in \mathbb{R} \mid 0 \leq x \leq 10\}\)
   - \(E = \{x \in \mathbb{R} \mid x \geq 5\}\)
   - \(F = \{x \in \mathbb{R} \mid x < 5\}\)

   Write each of the following in set builder notation:

   a) \(D \cap E\)  
   _________________________________

   b) \(D \cup F\)  
   _________________________________

   c) \(D - F\)  
   _________________________________

   d) \(E \cap F\)  
   _________________________________

   e) \(D^c\)  
   _________________________________

   f) **True or False?** Sets \(E\) and \(F\) form a partition of the set of reals.
