R1 U R2 is the relation that contains all pairs (a,b) such that a is congruent to b modulo 5 or modulo 7, or both.

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.)

Planar Graph (Self Doubt)
This is a graph ? Is it planar or not ? As per definition of planar graph it can be drawn in such a way that no edges cross each other. other theorems are if a connected simple graph is planar→ e<=3n-6 if a connected simple graph is planar → ... for planar graph not meet if the graph is planar but Now if i draw i dont intersect any edges .,which show it is planar
