Question: Let G = (V, E) be a bipartite graph with V partitioned as X Y, where X = {x1, x2, . . ., xm]

Let G = (V, E) be a bipartite graph with V partitioned as X ∪ Y, where X = {x1, x2, . . ., xm] and Y = {x1, x2, . . . , xn}- How many complete matchings of X into Y are there if
(a) m = 2, n = 4, and G = Km n?
(b) m = 4, n = 4, and G = Km,n?
(c) m = 5, n = 9, and G = Km,n?
(d) m < n and G = Km,n?
