2 10 (111) Switching Circuit. (a) Prove that the sum of degrees of all vertices in a graph is equal to twice of number of a edges. Also determine given graph has a Hamilton circuit or Euler circuit if it does not then give an argument to show why no such circuit exists: a d OR (b) Prove that following statements are logically equivalent or Tautology: 10 Page 1 of 3 (a) [(p19) V{q^(~r)}] → [{(~p) Ar}V{(~9)^(~r)}] (b) (p = q)^(r v q) = (p Vq)^(r)q
