#applied course
how many regions are in the above graph and please explain with region formula also. r=e-v+(c+1) my attempt is : r=5-5+2 r=2 but the rule is twice the no of boundary edges which is (5*2) = sum of region degrees which (4+5=9 ) can someone explain where the fault is

Self doubt
How many simple directed (unweighted) graphs on the set of vertices {v0,v1,…v5} are there that have at most one edge between any pair of vertices? (That is, for two vertices a, b, only at most one of the edges (a, b) and (b, a) is in the graph.)
