Probability of graph connectivity

  1. Aug 28, 2004 #1
    Hi guys
    I am Samir. I am new to this group and need some help regarding a question that involves probability of connectivity in graphs.

    The problem can be stated as:

    Given a random graph G(n,p) where n is number of nodes in the graph and p is the probability that an edge exits between two nodes, (when p=0 graph does not have any edges and when p = 1 graph is fully connected.) then if i take a subgraph of this random graph based on criteria that all the nodes of this subgraph are at a particular distance from one fixed node, then what is the probability that this subgraph is connected? I want to know whether this probability will be less than p, and if yes how much less?

    I hope this makes my question clear.

    Thanks

    Samir
