Let 0 < p < 1. consider a population of organisms whose lifecycle goes as follows. a newborn individual has probability p of reaching adulthood. once an adult, the individual gives birth to exactly two offspring, and then dies. start with a single (adult) individual. find the probability that this population eventually goes extinct.

Zero

Step-by-step explanation:

This situation could be modeled with a binomial distribution.

After n generations, the probability that there are exactly k adults would be

So, the probability that there are no adults after n generations is

The population would eventually go extinct if  

But, 0 < p < 1 as a consequence 0 < 1-p <1 and

Hence, the probability that the organism will go extinct is 0.

a framing bias

step-by-step explanation:

rodrigo is subject to a framing bias i believe.
