you guys know what this question is asking?
\[k_{m,n}\]
is a bipartite graph
\[k_n\]
is a complete graph of n vertices
\[W_y\] is a wheel with y+1 vertices where y vertices are arranged in a cycle and the y+1th vertex in adj to all the other y vertices
therefore a wheel W_n has an average degree of (4*n)/(n+1)
