Consider a branching process whose offspring generating function is o(s) = (1/6) + (5/6)s2. Obtain the probability of ultimate extinction. Enter your answer as an integer of the form m or a fraction of the form m/n. Do not include spaces. Consider a branching process whose offspring generating function is o(s) = (5/6) + (1/6)s?. Obtain the mean time to extinction. Write your answer to two decimal places. Do not include spaces. Use the Excel spreadsheet "Mean Time to Extinction" in the Resources section of the unit Moodle page to help you with the calculation.
