If so, is it proper or improper? Explain why, carefully. 3. Write all the improper subsets of set B. 4. Write the set C by enumeration. 5. Suppose the universal set U is all real numbers. Write the set C. 6. Of all the subsets of B, which one has the fewest number of elements? Consider the following sets. A {1,2,3,4), B (2,3,5), and C = {x|0 < - <6 and x is an integer }.
