If n(A) = 14, n(B) = 13, n(C) = 22, n(A $\rm \cap$ B $\rm \cap$ C) = 4, n(A $\rm \cap$ B) = 4, n(B $\rm \cap$ C) = 9, n(C $\rm \cap$ A) = 11, and n ($\rm \overline { A \cup B \cup C }$) = 4, then

1. Find the value of n(U).
2. Find the value of n($\rm A \cup B \cup C$).
3. Show the information in a Venn diagram.
4. Is A a subset of (B $\rm \cup$ C)? Give reason.
