10. You are studying a mutant mouse that you suspect will exhibit a longer lifespan than wild-type animals. You collect a group of 35 animals, of which 15 are mutant and 20 wild-type, and allow them to age. Of the last 10 animals to expire, 8 are mutant. What is the probability that 8 (or more) of the last 10 mice to die will be mutant if deaths occur at random in the population as a whole?
