#Question 1
#A and B, and there are a(n) labeled objects of size n in the A family, and b(n) in the B family.
#C = A X B
#If the size of the first component is k then the size of the second must be n-k.
#There are n choose k ways to decide which of the n labels are in the first component.
#There are a(k)b(n-k) ways to choose the objects for each component from the A and B families.
#If both sides are multiplied by x^n/n! and added up from n=0 to n=∞ then we get
#EGF(C)=EGF(A)*EGF(B)
#Question 2
#ogf: (6*x^3)/(x - 1)^4
