In a classroom of 50 students, each student is assigned a unique number from 1 to 50. Define Set \( A \) to be the set of students whose assigned numbers are multiples of 4, and Set \( B \) to be the set of students whose assigned numbers are multiples of 6. What is the cardinality of the intersection of Sets \( A \) and \( B \)? Let's think step by step and output the final answer within \boxed{}.
