- 4. [10 marks] Let T be the following tree: Find a graph G whose block graph BL(G) is isomorphic to T. Explain why your answer is correct.arrow_forward5. [10 marks] Determine whether the graph below has a perfect matching. Explain why your answer is correct. ข พarrow_forward(c) Utilize Fubini's Theorem to demonstrate that E(X)= = (1- F(x))dx.arrow_forward
- (c) Describe the positive and negative parts of a random variable. How is the integral defined for a general random variable using these components?arrow_forwardLet k ≥ 1, and let G be a k-regular bipartite graph with bipartition X, Y . Prove that |X| is the minimum size of a vertex cover in G.arrow_forward3. [10 marks] Let Go = (V,E) and G₁ = (V,E₁) be two graphs on the same set of vertices. Let (V, EU E1), so that (u, v) is an edge of H if and only if (u, v) is an edge of Go or of G1 (or of both). H = (a) Show that if Go and G₁ are both Eulerian and En E₁ = Ø (i.e., Go and G₁ have no edges in common), then H is also Eulerian. (b) Give an example where Go and G₁ are both Eulerian, but H is not Eulerian.arrow_forward
