each vertex of the graph 7. Prove that the order of any subgroup of a finite group divides the order of the group. 8. Let (A, v, ^,) be a Boolean Algebra. Show that (A, ) is an Abelian group, where is defined as ab=(a^ b)v (a^b). 9. Let (A, *) be a group. Let B be a subset of A such that 2|B| > |A|. Show that, for any a in A, b¹ | b = B). a= b₁ b₂ for some b₁1 and b₂ in B. (Hint: Consider set C = (a
