There are 6 numbered balls in a bag. Each ball has a distinct number and the numbers are in {1, 2, 3, 4, 5, 6}. Take 3 balls from the bag (without replacement) randomly and read the number on each ball. Let X1 be the maximum number and X2 be the minimum number among the three observed numbers. (a) Find the marginal p.m.f. of X1. (b) Find the marginal p.m.f. of X2. (c) Find the joint p.d.f. of X1 and...

Question 1 a) Prove that if u and v are distinct vertices of a graph G, there exists a walk from u to v if and only if there exists a path (a walk with distinct vertices) from u to v. b) Prove that a graph is bipartite if and only if it contains no cycles of odd length. Please write legibly with step by step details. Many thanks!

Consider an undirected graph G that has n distinct vertices. Assume n≥3. How many distinct edges will there be in any circuit for G that contains all the vertices in G? What is the maximum degree that any vertex in G can have? What is the maximum number of distinct edges G can have? What is the maximum number of distinct edges that G can have if G is disconnected?

A graph is G is semi-Eulerian if there are distinct vertices u, v ∈ V (G), u =v such that there is a trail from u to v which goes over every edge of G. The following sequence of questions is towards a proof of the following: Theorem 1. A connected graph G is semi-Eulerian (but not Eulerian) if and only if it has exactly two vertices of odd degree. Let G be semi-Eulerian with a trail t starting at...
