A graph has r = 4 vertices and n = 5 edges. Then how many spanning trees can be drawn.a. 20 b. 22c. 18d. None of Them
Question
Solution 1
The number of spanning trees for a graph can be calculated using the formula n^(r-2), where n is the number of edges and r is the number of vertices.
In this case, r = 4 and n = 5.
So, the number of spanning trees is 5^(4-2) = 5^2 = 25.
