    Branching Process

    P0=.5, P1=.1,P3=.4

    Suppose X0=1

    then
    What is the prob. that the population is extinct in the third generation, given that it was not extinct in the second generation?

    It looks simple, but I am getting different answer from my classmates...

    Thank you~~!

    Please post the entire question, or if that is it provide the context so we can underatand the system that is being modelled and the significance of the variables.

    Given a branching process with the following offspring distributions,

    p0=.5, p1=.1, p3=.4,

    and suppose X0=1,

    what is the probability that the population is extinct in the third generation, given that it was not extinct in the second generation?




    Sorry for the confusion..
