Question 10 Let (Xn)n5N be a branching process dened as in (8.1.1) in the script on page 310 with X0 = 1. Assume that the corresponding (Yang satisfy P(Yn=0}=ci P(Y= 1) =61! for strictly positive constants ca, (:1 > U satisfying (:0 + c1 = 1. Then the extinction probability of the branching process is equal to 1. ms No
