Step 1: Understand the problem. We are given two sets:
Set \( A \) with median \( m_1 = 2 \),
Set \( B \) with median \( m_2 = 4 \).
When combining sets A and B, the median of the combined set will depend on the values of \( m_1 \) and \( m_2 \), and the total number of elements in the two sets.
Step 2: Median of Combined Sets.
If the total number of elements in the combined set is even, the median lies between the medians of the two sets.
Since \( m_1 = 2 \) and \( m_2 = 4 \), the combined median will be at least 2 because the smallest median is 2, and no value smaller than 2 can lie between the two medians.
Step 3: Conclusion. Thus, we can say that the median of the combined set is at least 2. The correct answer is: \[ \boxed{{at least 2}}. \]
Five friends A, B, C, D, and E are sitting in a row facing north, but not necessarily in the same order:
B is to the immediate left of C
E is not at any of the ends
D is to the right of E but not next to C
A is at one of the ends
Who is sitting in the middle?
