"You are studying two organisms: A and B The proportion of offspring surviving is 0.05 (or 5%) for A and 0.1 (or 10%) for B. The average fecundity of A is 60 and for B it is 40. Which organisms has the higher fitness, A or B? You are studying the life tables of two species: A and B. They produce the same number of offspring throughout their lives , but the probability of females' surviving to a certain age differs. Which species has a higher reproductive success, A or B?"

Animal Offspring In a certain animal species, the probability that a healthy adult female will have no offspring in a given year is 0.29, while the probabilities of 1, 2, 3, or 4 offspring are, respectively, 0.23, 0.18, 0.16, and 0.14. Find the expected number of offspring.
