Discrete Math

Suppose you have sets \( A \) and \( B \) with \( |A| = 11 \) and \( |B| = 18 \).

a. What is the largest possible value for \( |A \cap B| \)?
- The answer given is 11.

b. What is the smallest possible value for \( |A \cap B| \)?
- The answer given is 0.

c. What are the possible values for \( |A \cup B| \)?
- The answer format indicates an inequality: \( \leq |A \cup B| \leq \).
  
The question is asking for the range of possible values for the size of the union of sets \( A \) and \( B \).
